How to Tell if You Have Windows 10 or Windows 11

The quickest way to tell whether you have Windows 10 or Windows 11 is to press Windows + R, type winver, and press Enter. The About Windows box shows Windows 10 or Windows 11 at the top, with the version and build number underneath.

You can also check in Settings > System > About, where Edition under Windows specifications shows the full name, such as Windows 11 Home.

Applies to: Windows 10 and Windows 11.

Check with winver

1. Press Windows + R to open the Run box.
2. Type winver and press Enter.
3. Read the name at the top (Windows 10 or Windows 11) and the Version line below it.

Check in Settings

1. Right-click Start and select System. Or open Settings and select System > About.
2. Scroll to Windows specifications.
3. Read these lines:

• Edition: the full name, such as Windows 11 Home, Windows 11 Pro, or Windows 10 Pro.
• Version: the feature update, such as 24H2 or 25H2.
• OS build: the exact build number.

Tell from the build number

If an app or website only shows a build number, you can still tell which Windows you have:

• Build 22000 or higher: Windows 11.
• Build 19045 or lower: Windows 10.

Tell at a glance

• Windows 11 has the Start button and app icons centered on the taskbar by default, and windows have rounded corners.
• Windows 10 has the Start button in the bottom-left corner, a search box next to it, and square window corners.

The Windows 11 taskbar can be moved to the left, so if you’re not sure, use winver.

Check from a command

If Settings won’t open, or you’re checking a PC remotely, open Command Prompt and run:

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

The OS Name line shows Microsoft Windows 11 or Microsoft Windows 10, followed by the edition. In PowerShell, Get-ComputerInfo | Select-Object OsName, OSDisplayVersion shows the name and the version, such as 25H2.

Check whether it’s 64-bit or ARM

Some apps need to know more than the Windows version. In Settings > System > About, look at System type. It shows 64-bit operating system, x64-based processor on most PCs, or ARM-based processor on PCs with Snapdragon chips. Windows 11 only comes in 64-bit, so a 32-bit result means you have Windows 10.

If the answer doesn’t look right

• winver shows Windows 11, but an app shows Windows 10. The app is reading the internal version number, which is still 10.0 on Windows 11. Trust winver.
• Settings and winver disagree on the version (such as 24H2 vs. 25H2). Restart the PC. A pending update can show one version before it finishes installing.
• You’re checking in a virtual machine or remote desktop. Run winver inside that session; it shows the remote system, not your own PC.

Why it matters

Instructions often differ between the two, so knowing which one you have saves time when you follow a guide. Some apps and games also need Windows 11.

Windows 10 support ended on October 14, 2025. A Windows 10 PC no longer gets security updates unless it’s enrolled in Extended Security Updates. You can enroll in Windows 10 Extended Security Updates, or upgrade Windows 10 to Windows 11 for free if your PC qualifies.

Frequently asked questions

Why does my Windows 11 PC say version 10.0?

Windows 11 still uses the internal version number 10.0, so Command Prompt, System Information, and some apps show 10.0 followed by the build. Check the build number or use winver to be sure.

Do I have Windows 11 Home or Pro?

Check Edition in Settings > System > About. Pro adds features such as BitLocker Drive Encryption and the ability to host Remote Desktop connections.

How do I know if my PC can run Windows 11?

Use Microsoft’s PC Health Check app. It tells you whether your PC meets the requirements and, if not, which one it fails.

How long does Windows 10 Extended Security Updates last?

For home users, the Extended Security Updates program runs until October 12, 2027. After that, Windows 10 PCs at home get no more security fixes, so plan to move to Windows 11 or a new PC.
