How to Check Your Windows 10 Version

To check your Windows 10 version, press Windows logo key + R, type winver, and press Enter. The About Windows box shows the version, such as 22H2, and the OS build number. For the edition and whether Windows is 32-bit or 64-bit, select Start > Settings > System > About.

Applies to: Windows 10.

22H2 is the final version of Windows 10. Windows 10 reached end of support on October 14, 2025, so if you see an older version, install the latest updates.

Check with winver

1. Press Windows logo key + R.
2. Type winver and press Enter.
3. Read the Version and OS Build line.

Check in Settings

1. Select Start > Settings > System > About.
2. Under Device specifications, System type shows 64-bit or 32-bit.
3. Under Windows specifications, see the Edition (Home or Pro), Version, and OS build.

What the numbers mean

• Version: the year and half of the year the update came out. 22H2 means the second half of 2022.
• OS build: 19045 is Windows 10, version 22H2, and 19044 is version 21H2. The number after the dot rises with each monthly update, so a higher number means a more up-to-date PC.
• Edition: Home, Pro, Enterprise, or Education. Some features, such as BitLocker and Remote Desktop hosting, need Pro or higher.

Check with PowerShell

In PowerShell, run this to see the version name, such as 22H2:

• (Get-ItemProperty “HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion”).DisplayVersion

Check with Command Prompt

Open Command Prompt and run systeminfo. Look at OS Name, OS Version, and System Type near the top. The ver command shows just the build number.

If the version looks wrong

• It shows an older version, like 21H2. Your PC missed the last feature update. Go to Settings > Update & Security > Windows Update and install what’s offered.
• The edition shows LTSC. Long-Term Servicing Channel editions are made for businesses and special devices, and they follow their own support dates.
• You’re not sure you still get security updates. Since free support ended, Windows 10 PCs need Extended Security Updates. Windows Update shows whether your PC is enrolled.
