How to check your Windows version and build

Find out in a few seconds which Windows version and build you have, to know which updates apply to you.

All guides Paste build in Update History Check →

Update notes talk about versions (like 24H2 or 25H2) and builds (like 26100.9445). Here is how to find yours.

The quickest way: winver

  1. Press Windows + R.
  2. Type winver and press Enter.
  3. A small window shows, for example, Version 24H2 (OS Build 26100.9445).

The part before the dot (26100) tells the version, the part after the dot (9445) tells how up to date it is: a higher number means a newer update.

From Settings

  1. Open Settings › System › About.
  2. Under Windows specifications you'll see the Edition (Home, Pro, Enterprise), the Version and the OS build.

With PowerShell (also on Windows Server)

On a server without a desktop, or to copy the result, run this in PowerShell:

PowerShell
> Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' | Select-Object DisplayVersion, CurrentBuild, UBR, EditionID

CurrentBuild and UBR together are the build: 26100 and 9445 mean 26100.9445. The output shows nothing about you or your PC, so you can paste it into the update history tool. (Windows 11 still says "Windows 10" in some registry names: trust the build number.)

Which product the build belongs to

Some builds are shared: 26100 is Windows 11 24H2 and Windows Server 2025, 17763 is Windows 10 Enterprise LTSC 2019 and Windows Server 2019, 14393 is Windows 10 Enterprise LTSB 2016 and Windows Server 2016. winver and Settings name the product; in PowerShell, EditionID says "ServerStandard" or "ServerDatacenter" on Windows Server and "EnterpriseS" on the long-term servicing editions.

Why the edition matters

Home and Pro editions stop getting updates earlier than Enterprise and Education editions of the same version. Windows Server and the long-term servicing editions (LTSB and LTSC) have one date for all editions, except Windows 10 IoT Enterprise LTSC 2021, which gets updates for five more years than Windows 10 Enterprise LTSC 2021. The calendar lists the dates.

What to do with it

Open the page of your version from the home page to see its latest update, or paste the "OS Build" line into the update history tool.
