“What Windows do I have?” sounds like a beginner’s question until the moment it matters — installing software that needs a specific version, calling support, checking whether your PC still gets security updates, or buying an upgrade key and needing to know your starting point. Then everybody googles it, beginners and IT veterans alike.
The answer takes under a minute to find. Here are the two fastest ways, what every field on that screen actually means, and — the part most guides skip — what your answer means for you in 2026, because a couple of these results come with deadlines attached.
The 10-second method: winver
- Press the Windows key + R together. A small Run box opens.
- Type winver and press Enter.
A window pops up with your Windows version at the top — “Windows 11”, “Windows 10” — followed by a version number like 23H2 or 22H2 and a build number. That’s usually everything you came for.

Five more ways to check, and when each one is the right tool
The winver box answers the question in ten seconds, and for most people that is the end of it. But there are situations where you need more than a version number — you are on the phone with support, you are writing down specifications for a dozen machines, or the person asking you what Windows do I have is actually asking something slightly different. Each of the methods below tells you something the others do not.
System Information, for the complete picture
Hold the Windows key and press R, type msinfo32, and press Enter. The System Summary page that opens is the most complete single view Windows offers of itself.
Read down the right-hand column. OS Name gives you the version and edition together, so you see Windows 11 Pro rather than just Windows 11. Version gives the build number. System Type tells you whether you are running 64-bit or 32-bit. System Manufacturer and System Model identify the physical machine, which matters when you are looking up drivers. BIOS Mode shows UEFI or Legacy, and Secure Boot State shows On or Off — the two rows that decide whether a machine can move to Windows 11.
This is the screen to use when someone asks you for specifications. Everything is on one page, and you can select the rows and copy them straight into an email.
Command Prompt, for a copyable one-line answer
Press the Windows key, type cmd, and open Command Prompt. Type systeminfo and press Enter. After a few seconds you get a full report including OS Name, OS Version, the original install date, the last boot time, and the total physical memory.
If you want just the version line without the rest, type ver instead and you get a single line with the build number. This is the fastest method when you are already in a terminal, and the output is text you can copy without retyping.
PowerShell, when you need it for several machines
Open PowerShell from the Start menu and run this command: Get-ComputerInfo | Select WindowsProductName, WindowsVersion, OsHardwareAbstractionLayer. You get a compact, structured answer that is easy to script across multiple computers.
Anyone managing a handful of machines rather than one will find this the practical method, because the same command can be pointed at other computers on the network and the results collected into a single list. For a single home PC it is more effort than winver for the same answer.
System Properties, for the classic view
Open File Explorer, right-click This PC in the left-hand pane, and choose Properties. On Windows 11 this opens the modern Settings page. On Windows 10 and earlier it opens the old System window, which shows the Windows edition, the system type, and importantly the activation status at the bottom.
The reason to know this route is that it works on every version of Windows going back many years, which makes it the reliable choice when you are looking at an unfamiliar or genuinely old machine.
DirectX Diagnostic Tool, for gaming and graphics questions
Windows key and R, type dxdiag, press Enter. The System tab shows the operating system, the system model, the processor, the memory, and the DirectX version. The Display tab shows the graphics hardware and its driver date.
If the question what Windows do I have came from a game or an application refusing to install, this is the screen the support forum will ask you for, because it covers the operating system and the graphics stack together.

Which method should you actually use?
| What you need | Best method | Takes under a minute |
|---|---|---|
| Just the version number, fast | winver | Yes |
| Version plus edition plus activation | Settings, System, About | Yes |
| Full specifications for a support ticket | msinfo32 | Yes |
| Copyable text output | systeminfo in Command Prompt | Yes |
| Several machines at once | PowerShell | No |
| Graphics or gaming problem | dxdiag | Yes |
| A very old or unfamiliar PC | System Properties | Yes |
The full-detail method: Settings
- Press Windows key + I to open Settings.
- Go to System, then About (bottom of the list).
This screen shows more: edition (Home, Pro, Enterprise), version, build, plus whether your Windows is 64-bit and what processor and RAM the machine has. It’s the screen a support person means when they ask “what are you running?”
What the fields mean, in one table
| Field | Example | What it tells you |
|---|---|---|
| Edition | Windows 11 Pro | The product tier — decides features like BitLocker and Remote Desktop |
| Version | 24H2 | The yearly feature release — year plus half (24H2 = second half of 2024) |
| OS build | 26100.2033 | The exact patch level — mostly for support calls |
| System type | 64-bit | Which software installers you should download |
32-bit or 64-bit: the other question hiding inside this one
A good share of the people searching what Windows do I have are really being asked something more specific by a download page: is your Windows 32-bit or 64-bit? Getting this wrong is the most common reason an installer refuses to run.
To check, open Settings, go to System, then About, and read the line labelled System type. It says one of three things. Sixty-four-bit operating system with an x64-based processor means you have a 64-bit Windows on 64-bit hardware, which is the normal situation on any machine made in the last fifteen years. Thirty-two-bit operating system with an x64-based processor means your hardware could run 64-bit Windows but a 32-bit version was installed — usually on an old machine that was upgraded in place many times. Thirty-two-bit operating system with an x86-based processor means genuinely old hardware that cannot run 64-bit at all.
Why it matters more than it sounds
A 32-bit Windows cannot address more than about 4GB of memory, and in practice usable memory sits closer to 3.2GB. If you have 8GB or 16GB installed and Windows reports only a fraction of it as usable, a 32-bit installation is almost always the explanation, and no amount of adding memory will help.
It also decides what software you can run. Sixty-four-bit applications will not install on a 32-bit Windows at all, and the pool of 32-bit software is shrinking every year as developers drop it. Modern Windows 11 is 64-bit only, so a 32-bit installation is also a dead end for upgrading.
Moving from 32-bit to 64-bit
This is worth knowing because people assume it is a setting. It is not. There is no in-place switch from a 32-bit Windows to a 64-bit one — it requires a clean installation, which means backing up your files, installing fresh, and reinstalling your applications.
The good news is that the licence usually carries across, because a Windows licence covers the edition rather than the architecture. If your machine has 64-bit-capable hardware and more than 4GB of memory, the clean install is worth the afternoon it costs. Our guide on creating a bootable USB walks through the installation media step, and if activation gives you trouble afterwards, the Windows key not working guide covers the fixes.
Which edition do I have, and does it matter?
Version and edition are two different things, and confusing them causes real problems when buying software or joining a work network. Version is Windows 10 or Windows 11. Edition is Home, Pro, Enterprise or Education. Both appear on the Settings, System, About page, on the line labelled Edition.
| Edition | Who normally has it | Can join a company domain | Has BitLocker drive encryption | Has Remote Desktop host |
|---|---|---|---|---|
| Home | Most PCs bought from a shop | No | No | No |
| Pro | Business machines and enthusiast builds | Yes | Yes | Yes |
| Enterprise | Issued by a company IT department | Yes | Yes | Yes |
| Education | Issued by a school or university | Yes | Yes | Yes |
Three moments make the edition matter. If your workplace asks you to join the company domain and you have Home, you cannot — that is a Pro feature and no setting will enable it. If you want to connect to your PC remotely from elsewhere, hosting a Remote Desktop session requires Pro. And if you need to encrypt the drive on a laptop that leaves the house, BitLocker is a Pro feature too.
If you find you have Home and need Pro, you do not reinstall anything. Windows supports an in-place edition upgrade that keeps your files and applications exactly where they are — you enter a Pro key and the machine converts in a few minutes. Our comparison of Windows 11 Home vs Pro covers whether that upgrade is worth it for you, and the Windows 10 Home vs Pro guide does the same for the older version.
Equally, if you have Pro and only ever browse, write and watch things, you are not missing anything by not using its extra features, and there is no reason to feel you should be.
No Settings app? Identifying older Windows by sight
If Windows key + I opens nothing recognizable, you’re likely on something older. Quick visual identification: a Start button that opens full-screen colorful tiles is Windows 8 or 8.1; a round Start orb with a search box and glassy transparent window edges is Windows 7; centered taskbar icons are Windows 11; left-aligned icons with a tiled Start menu are Windows 10. The winver command works on all of them.
Is my Windows activated, and is it genuine?
Once you know what Windows you have, the natural follow-up is whether it is properly licensed. These are separate questions, and a machine can report a perfectly normal version while sitting on a licence that will not survive its next reinstall.
The quick check
Open Settings, go to System, then Activation. One of three things appears. Windows is activated with a digital licence linked to your Microsoft account is the best outcome — the entitlement lives on Microsoft’s servers and follows your account, so reinstalling is painless. Windows is activated with a digital licence means the entitlement is tied to this hardware; it survives a reinstall on the same machine but is harder to move. Windows is not activated means there is a problem to solve.
The deeper check most people never run
The activation screen tells you whether Windows accepted a licence. It does not tell you what kind of licence it accepted, and that distinction is where trouble hides.
Open Command Prompt as an administrator — press the Windows key, type cmd, right-click Command Prompt and choose Run as administrator. Type this and press Enter: slmgr /dli. A small window appears showing the licence description and the last five characters of the product key.
Read the description line carefully. If it mentions RETAIL, you have a full retail licence, which is transferable to another machine and the most durable kind. If it mentions OEM, the licence is bonded to this motherboard permanently — fine where it is, but it cannot legitimately move to a new computer. If it mentions VOLUME or KMS, that is a licence type intended for organisations, and on a home machine it is a strong sign the key came from somewhere it should not have. Volume licences frequently reactivate against a server every 180 days, which is exactly how a machine that has worked fine for months suddenly reports itself unlicensed.
For more detail run slmgr /dlv, which shows the same information plus the activation ID and, for volume licences, the renewal interval. If you see a renewal interval on a home PC, you now know why your activation keeps lapsing.
What to do if the licence is not what it should be
If the check turns up a volume or KMS licence on a personal machine, the fix is straightforward: buy a proper retail licence and enter it. You do not need to reinstall Windows or lose any files. Go to Settings, System, Activation, choose Change product key, and enter the new one. The system re-licenses itself in place, usually in under a minute.
The reason to do this rather than leave it is not moral, it is practical. An improperly licensed machine fails future upgrade paths, can lose activation without warning, and cannot be helped by Microsoft support when something goes wrong. Putting it on genuine Microsoft license keys takes it off that list permanently. If you want the full explanation of how the resale market works before spending anything, is it safe to buy cheap Microsoft license keys is the honest version, including the parts that do not flatter our own industry.
Reading your build number like a technician
The number winver shows you is not decoration. Once you know how to read it, it tells you how current your machine is and whether a problem you are chasing has already been fixed.
A Windows version string has two parts. The version label, something like 23H2 or 24H2, tells you which half of which year that feature update was released — 24H2 means the second half of 2024. The build number, the longer figure in brackets, identifies the exact update level, and the digits after the full stop tell you which monthly patch you are on.
Why the build number is the useful part
Three situations where it matters. When a support article says a bug was fixed in a particular build, comparing your number to theirs tells you immediately whether you already have the fix or need to update. When software lists a minimum supported build, you can check without guessing. And when a machine behaves strangely after an update, the build number is the first thing any technician will ask for.
Two machines can both report Windows 11 and be a year apart in patches. The version name alone hides that. The build number does not.
Checking whether you are behind
Open Settings, go to Windows Update, and click Check for updates. If it reports you are up to date, your build is current for your machine. If it offers a feature update, you are a release behind, which is often deliberate on managed machines and accidental on home ones.
One thing worth knowing: Windows sometimes holds a feature update back from specific hardware because of a known compatibility problem with a driver or a device. If Windows Update says your PC is not quite ready, that is not a fault, and forcing the update past that hold is how people create problems they then have to fix.
[image: The winver dialog box with the version label and build number circled and annotated to show what each part means]
Now the important part: what your answer means
You have Windows 11
You’re current. Nothing to do except let updates run. If you’re on Home and keep bumping into missing features like BitLocker, the Home vs Pro comparison shows what an upgrade key unlocks.
You have Windows 10
You have a deadline. Regular support ended in October 2025 and the consumer security-update extension runs out in October 2026 — very soon. Your realistic options (free upgrade, LTSC, new machine) are ranked honestly in our Windows 10 end of support guide, and the first step is checking your PC against the Windows 11 requirements.
You have Windows 7 or 8.1
That machine has been unpatched for years and shouldn’t touch online banking. If the hardware still has life in it, the escape route is a cheap genuine license and a clean install — the Windows 7 to 10 upgrade guide walks the whole path, and genuine Windows keys cost less than most people’s lunch budget for the week.
The screen says “Windows is not activated”
Different problem — that’s licensing, not version. A watermark in the corner and locked personalization settings mean Windows is running unlicensed; a genuine key and five minutes with the activation guide fix it permanently.
Checking Windows on a computer that is not in front of you
A lot of the time the person asking what Windows do I have is asking on someone else’s behalf — a parent on the phone, a colleague across an office, a machine in another room. These are the routes that work at a distance.
Talking someone through it
The instruction that works over the phone with anyone, regardless of how comfortable they are with computers, is this: hold down the key with the Windows logo, tap the letter R, let go, type the word winver, and press Enter. Then read me everything in the little box.
It works because it needs no menu navigation, no scrolling and no reading of small text before the answer appears. Asking someone to open Settings and find About involves four or five steps where they can get lost. Winver involves one.
Over the network
If you have administrative access to the machine and it is on the same network, PowerShell can ask it directly. Running Get-ComputerInfo with a computer name parameter returns the version details from a remote machine without anyone touching it. This requires remote management to be enabled, which it usually is on domain-joined business machines and usually is not on home PCs.
For a small office, this is the fastest way to build an inventory of who is on which version before planning an upgrade — and knowing that inventory is exactly what stops an upgrade project from turning into a series of surprises.
From a machine that will not boot
If the PC does not start, you can still identify the Windows version on the drive. Boot from installation media, choose Repair your computer, then Troubleshoot, then Command Prompt. From there you can browse the Windows folder on the drive and read the version information out of the registry hive.
This is a technician’s route rather than a home one, but it matters in one common scenario: recovering data from a dead machine and needing to know what licence was on it before rebuilding.
What to do next, based on what you found
Everything above answers the question. This section answers the reason you asked it.
You found Windows 11, activated
Nothing to do. You are on the current version with a valid licence. Keep Windows Update running and check the activation screen once a year out of habit. If the licence is a digital one not yet linked to a Microsoft account, linking it is ten minutes well spent — it makes any future reinstall or motherboard replacement dramatically easier.
You found Windows 10, activated
This is the situation that needs a decision rather than an action. Windows 10 reached end of support in October 2025, and the consumer Extended Security Updates bridge runs out in October 2026. After that, no security patches.
Check whether the machine can take Windows 11 by looking at the msinfo32 rows described earlier — UEFI, Secure Boot, TPM 2.0, and a supported processor. If it passes, upgrade before the deadline rather than during it. If it fails, our guide on Windows 10 end of support lays out the realistic options, including the ones that do not involve buying a new computer.
You found Windows 7, 8 or 8.1
These are years past support and should not be used for anything involving banking, email or personal files. The upgrade path depends on the hardware: many machines from that era can run Windows 10, and some can run Windows 11. Our walkthrough on how to upgrade Windows 7 to Windows 10 covers the process including what happens to your files.
You found Windows is not activated
Deal with this before anything else, because an unactivated Windows blocks personalisation settings, nags continuously, and closes off future upgrade paths. Sometimes it is a simple fix — a key that needs re-entering after a hardware change, or a digital licence that needs the account linked. Sometimes it means the machine was never properly licensed. Either way, a genuine Windows licence resolves it in about a minute through Settings, with no reinstall and no data loss.
A short history of Windows versions, so the numbers make sense
Part of the confusion behind the question what Windows do I have is that Microsoft’s naming has been inconsistent for two decades. A quick tour makes every number you might see on your screen legible.
Windows 7, and why people still miss it
Released in 2009, Windows 7 is the version people remember most fondly, largely because it followed Windows Vista and fixed almost everything wrong with it. Support ended in January 2020. If your machine reports Windows 7, it has been without security updates for years.
Windows 8 and 8.1, the detour
Windows 8 arrived in 2012 built around a full-screen tile interface designed for touch, on a market that was overwhelmingly using a mouse and keyboard. It removed the Start button. The reaction was severe enough that Windows 8.1 brought the button back a year later. Both are long out of support.
Why there was never a Windows 9
Microsoft skipped straight from 8.1 to 10. The company never gave a definitive public reason, and the explanations offered range from wanting to signal a clean break after the Windows 8 reception to a widely repeated story about older software checking version names and mistaking a 9 for the much older Windows 95 and 98. Whatever the truth, there is no Windows 9, so if a site offers you one, it is not a real product.
Windows 10 and the last version that was not
Windows 10 launched in 2015 and was described early on as the last version of Windows — the idea being that it would be updated continuously rather than replaced. That framing lasted six years.
What it left behind is the version-and-build naming you now see in winver. Instead of new product names, Windows 10 shipped feature updates labelled by year and half — 1809, 1903, 20H2, 21H2, 22H2. This is why two Windows 10 machines can differ substantially while both calling themselves Windows 10. Support ended in October 2025, with the consumer Extended Security Updates bridge running to October 2026.
Windows 11 and the hardware line
Windows 11 arrived in 2021 and did something no consumer Windows release had done before: it drew a hard hardware line. TPM 2.0, Secure Boot, UEFI firmware and an approved processor list became requirements rather than recommendations. Millions of perfectly functional PCs were excluded, and that decision is still the most contested thing about the release.
It kept the yearly feature-update naming — 21H2, 22H2, 23H2, 24H2 and onward — which is why your winver box shows a version label alongside the name. Windows 11 is the current version, and despite persistent rumors, Microsoft has not announced a numbered successor.
Five mistakes people make identifying their Windows version
These come up constantly in support conversations, and each one sends someone down a wrong path.
Confusing the version with the edition. Windows 11 is the version, Pro is the edition. Someone told they need Windows 11 Pro who checks and sees Windows 11 has answered only half the question. Look at the Edition line specifically.
Trusting the desktop wallpaper. People identify their Windows by how it looks, and looks are the least reliable signal there is. Windows 10 can be themed to resemble Windows 11 and vice versa, third-party Start menu replacements change the whole appearance, and business machines often run a corporate theme that resembles nothing in particular. Read winver, not the screen.
Assuming the sticker on the case is current. A laptop with a Windows 7 sticker underneath may well have been upgraded twice since. The sticker records what shipped, not what is installed, and the sticker key is frequently not the key in use.
Reading the wrong number as the version. In the winver box, the version label and the build number sit close together, and people report one when asked for the other. If support asks for your build, they want the longer number in brackets.
Ignoring the activation state entirely. The most consequential omission on this list. Knowing you have Windows 11 Pro tells you nothing about whether the licence behind it is durable, and the machines that cause their owners the most grief are usually the ones running a correct-looking version on a licence that was never legitimate. The slmgr check described earlier takes twenty seconds and answers it.
Write it down once: the record worth keeping
Everybody looks this up, gets their answer, and forgets it within a week. Then the next time something breaks they look it up again. Five minutes now saves that loop forever, and it turns a vague question into a document you can hand to anyone helping you.
Open msinfo32, and note down six things for each computer you own: the Windows version and edition, the build number, the system type, the manufacturer and model, whether Secure Boot reads On, and whether the activation screen reports a digital licence linked to your Microsoft account. Add the date you checked. Keep it in a note, a password manager entry, or a printed page in a drawer — anywhere that is not only on the machine itself.
The value shows up at three moments. When you call support, you read the answers instead of hunting for them while someone waits. When you plan an upgrade, you know instantly which machines qualify and which do not, without touching any of them. And when a computer fails completely, you still have its licence details, which is the difference between a smooth rebuild and an afternoon of guessing.
One habit that prevents most licence headaches
If there is a single thing worth doing after identifying your Windows, it is linking the digital licence to a Microsoft account. Open Settings, System, Activation, and if it offers to add a Microsoft account, do it.
The reason is what happens later. A digital licence tied only to hardware is bound to that motherboard. Replace the motherboard, or have it replaced during a repair, and Windows deactivates with no straightforward way to reclaim it. A licence linked to an account can be reclaimed through the activation troubleshooter in a couple of clicks, because Microsoft can see the entitlement is yours. It costs nothing and takes two minutes, and the people who most regret skipping it are the ones who discover the difference on the day a machine comes back from a repair shop.
And if the answer you found was uncomfortable
Some people run this check and discover something they were not expecting — an unactivated system, a volume key on a home PC, or a version that stopped receiving security updates a while ago. That is not a bad outcome. It is the same information you had before, except now you can act on it.
None of those situations requires a new computer, and most of them do not require reinstalling anything. An unactivated or improperly licensed machine takes a genuine key entered through Settings and about a minute. An out-of-support Windows 10 machine that passes the hardware checks takes an in-place upgrade that keeps your files. Only genuinely old hardware that fails multiple requirement checks needs a bigger conversation, and even then there are options short of replacement.
What Windows do I have — FAQ
How do I check if my Windows is 32-bit or 64-bit?
Settings, System, About — “System type” says it outright. Virtually every PC from the last decade is 64-bit, but the field exists precisely because “virtually” isn’t “all”.
Does my Windows version affect which software I can install?
Increasingly, yes. New apps routinely require Windows 10 or 11, and more each year require 11 specifically. This — more than any Microsoft deadline — is what eventually forces upgrades: the software you want stops meeting you where you are.
How do I find my Windows product key?
Modern activation is usually a digital license tied to the machine — there may be no typed key to find, and after sign-in with your Microsoft account, reactivation is automatic. Keys you bought are in your purchase email; at KYMakers that email is your permanent record, so it’s worth an archive folder.
Is version 22H2 still okay to run on Windows 10?
22H2 is Windows 10’s final version — there is no newer one to move to. Whether it’s “okay” is now a support-deadline question rather than a version question; see the end-of-support guide above and pick your route before October.
What Windows do I have if winver will not open?
If the Run box does not appear or winver does nothing, try Command Prompt instead: press the Windows key, type cmd, open it, then type ver and press Enter. If that also fails, right-click This PC in File Explorer and choose Properties, which works on every version of Windows ever shipped. A machine where none of these three work has a deeper problem than an unknown version, and the next step is a repair rather than an identification.
How do I find my Windows product key on this PC?
For a licence embedded in the firmware by the manufacturer, open Command Prompt as an administrator and run: wmic path softwarelicensingservice get OA3xOriginalProductKey. If a key appears, that is the OEM key built into the motherboard. If the command returns nothing, your Windows is activated through a digital licence or a key entered manually, and there is no retrievable key to display — the entitlement lives on Microsoft’s servers rather than on the machine. Note that a digital licence is not a problem; it is the more convenient arrangement, because it survives reinstalls without you typing anything.
Can I tell what Windows I have without turning the computer on?
Not reliably. The sticker on the case or under the battery records what the machine originally shipped with, which is often several upgrades out of date. The model number can tell you roughly when it was made and therefore what era of Windows it came with, but nothing beats booting it and running winver.
Does knowing my Windows version tell me if I can upgrade to Windows 11?
Only partly. The version tells you where you are starting from, but eligibility depends on hardware: TPM 2.0, Secure Boot, UEFI firmware, a supported processor, and enough memory and storage. Run msinfo32 to check the firmware rows and tpm.msc to check the TPM. Our Windows 11 requirements guide walks through each check and what to do when one of them fails.
My PC says Windows 11 but everything looks like Windows 10. What is going on?
Almost certainly a theme or a third-party Start menu replacement, both of which are common on machines set up by someone who preferred the older look. Trust winver over appearance. The other possibility, on a work machine, is a corporate policy configuration that restores older interface behaviour deliberately.
Do I need to know my build number for anything practical?
Yes, in three situations: when a support article states a fix arrived in a specific build and you need to know whether you have it, when software lists a minimum supported build, and when you are reporting a problem to any technician, because it is the first thing they will ask. For everyday use the version name is enough.
Will checking what Windows I have change anything on my computer?
No. Every method on this page is read-only. Winver, msinfo32, systeminfo, dxdiag and the slmgr licence check all report information without altering a setting, installing anything, or contacting Microsoft. You can run all of them on a machine you do not own without leaving a trace beyond a window you closed.
Someone is selling me a used PC. What should I check before paying?
Run four checks in front of the seller. Winver, for the version and build. The Settings activation page, to confirm it says activated. The slmgr licence check in an administrator Command Prompt, to see whether the licence is retail, OEM or volume — a volume licence on a used home PC is a reason to walk away. And msinfo32, to confirm the machine reports UEFI, Secure Boot available and a TPM, which decides whether it has any upgrade future. A seller who will not let you run four read-only commands has told you something useful.
