Check your Windows version, edition and OS build

Before you start

You don't need an administrator account to read this information. Each method shows a slightly different set of details, so it helps to know more than one¹.

Three facts describe your Windows. The edition is the product, such as Home, Pro or Enterprise. The version is the feature update, such as 25H2, and the OS build is the number tied to it, such as 26200⁴.

Steps

1. Open About in Settings. Select Start > Settings > System, then select About¹.

2. Read Windows specifications. Under Windows specifications, check the Edition, Version and OS Build^1,2.

3. Check 32-bit or 64-bit. Under Device specifications, check the processor, the installed RAM and whether Windows is 32-bit or 64-bit².

4. Or use winver. Type "winver" in the search bar and press ENTER¹. The About Windows box opens with the version details¹. Type "msinfo32" instead to open System Information¹.

5. Or use a command. At the Command Prompt or in PowerShell, type this command and press ENTER¹:

   Command PromptCopy

   systeminfo | findstr /B /C:"OS Name" /B /C:"OS Version"

   In Command Prompt, ver shows the operating system version number³. In Windows PowerShell, use this instead³:

   PowerShellCopy

   $PSVersionTable.BuildVersion

Check it worked

Match the first part of your OS build to the version in Microsoft's release table⁴:

• Version 26H2: OS build 26300⁴
• Version 26H1: OS build 28000⁴
• Version 25H2: OS build 26200⁴
• Version 24H2: OS build 26100⁴
• Version 23H2: OS build 22631⁴

The number after the dot is the revision. It rises with each monthly update, for example 26200.9550⁴.

Common problems

• ver does nothing useful in PowerShell. The ver command works in Command Prompt (cmd.exe) but not in any version of PowerShell³. In PowerShell 7, use $PSVersionTable.OS instead³.

• You need to know if the PC runs LTSC. Long-Term Servicing Channel builds leave out many in-box apps, such as Microsoft Edge and Microsoft Store¹. Run this command and look for "EnterpriseS" in the output¹:

  Command PromptCopy

  slmgr /dlv

• Your PC is not offered 26H1. Version 26H1 is for new devices that came to market in early 2026⁴. It isn't offered as an in-place update from 24H2 or 25H2⁴.

• The About page says Windows 10. Support for Windows 10 ended on October 14, 2025². Microsoft recommends moving to Windows 11².

Questions

What is the difference between the Windows version and the OS build?

The version names the feature update, such as 25H2⁴. The OS build is a number tied to that version, such as 26200, followed by a revision that changes with each monthly update⁴.

How often does Windows 11 get a new version?

Windows 11 gets one feature update a year, released in the second half of the calendar year⁴. Home and Pro editions get 24 months of support for each version, and Enterprise and Education editions get 36 months⁴.

Is my Windows 11 version still supported?

Check the version against Microsoft's release information table⁴. For Home and Pro editions, updates end for 24H2 on 2026-10-13 and for 25H2 on 2027-10-12⁴.

How do I know if Windows is 32-bit or 64-bit?

Go to Settings > System > About². Under Device specifications, Windows shows whether the device runs a 32-bit or 64-bit version².
