How to Find Windows 11 Build Number

Difference between Version and Build Number

A Version (like 23H2 or 24H2) refers to a major feature update that Microsoft releases about once a year. A Build Number changes more often, usually during monthly Patch Tuesday updates. The number has two parts: the main build (such as 22631) and a revision after the dot (such as 22631.4602). The revision goes up with each cumulative update.

These updates usually carry KB numbers. A KB number is a Knowledge Base tracking code that Microsoft uses to catalog individual patches. If support asks which update you have, the full build number (main build plus revision) is the most useful thing to give them.

Method 1Use the About Windows screen

It works on every edition of Windows 11, including Home and Pro, and needs no admin rights.

1. Press Win+R on your keyboard. The Run box opens in the lower-left corner of the screen.
2. Type winver and press Enter.

A small window pops up showing your Windows version and build number. Look for the line that starts with “Version”, for example “Version 23H2 (OS Build 22631.xxxx)”. The window also shows your Windows edition and the Microsoft license terms. Click OK to close it. Nothing on your system has changed, so there is nothing to undo.

Method 2Use the Settings app

Another way to find this information is through the Windows Settings app. It shows more detail than the small window above, including your edition and the date Windows was installed.

1. Open the Start menu ⊞ and click Settings (or press Win+I). The Settings ⚙️ app opens.

2. Click System on the left-hand menu. The System page opens on the right.

3. Scroll down and click About. It is near the bottom of the list, so you may need to scroll a fair way.

4. Look under Windows specifications. You will see your build number listed there, next to OS build. The Edition and Version lines sit just above it.

You can click the Copy button next to the section if you need to paste the details into a support ticket or an email.

Method 3Use Windows Terminal

If you are comfortable with the command line, the Terminal app offers a quick way to view the build number. This is handy when you are already working in a terminal or connected to the machine remotely.

1. Right-click the Start button and select Terminal. Note: This may require admin privileges. If you get an access error, close the window, right-click Start again, and choose the Terminal (Admin) entry instead.
2. In the window, type ver and press Enter. The result prints on the next line or lines.

Read the number from the output. It is the same build number the other two methods show.

🪟 Windows 11 Servicing Channels

The General Availability channel targets home users. The LTSC (Long-Term Servicing Channel, a specialized edition built for strict enterprise stability) is typically reserved for corporate environments. Knowing your build helps clarify which servicing channel manages your operating system.

For most people this is only a point of interest. If you run Home or Pro, you are on the General Availability channel. If you are unsure, check the Edition line in Settings › System › About.

Summary

Locating a Windows 11 build number requires minimal effort using a command, the Settings menu, or the Terminal app. Keeping this build current ensures the computer remains secure and compatible with modern software. To check for newer builds, open Settings › Windows Update and install anything that is waiting. Visit the Microsoft Release Health page to review further details.
