Difference Between Windows 11 Version, Edition, and Build Number
Windows 11 version, edition, and build number are related, but they represent different aspects of your operating system.
Understanding these terms helps you identify exactly which Windows installation is running on your computer.
| Term | Meaning | Example |
|---|---|---|
| Windows Edition | Identifies the installed Windows product edition | Windows 11 Pro |
| Windows Version | Identifies the feature release | 26H2 |
| OS Build | Identifies the underlying operating system build | 26300 |
| Build Revision | Identifies the specific servicing update | 9818 |
Windows Edition
The Windows edition identifies which version of the Windows product you have installed. Common editions include Windows 11 Home, Pro, Education, and Enterprise.
Different editions offer different features, licensing options, and management capabilities.
Windows Version
The Windows version identifies the feature release installed on your computer.
Examples include
- Windows 11 23H2
- Windows 11 24H2
- Windows 11 25H2
- Windows 11 26H2
Microsoft uses these version labels to identify major Windows feature releases.
OS Build Number
The OS build number identifies the underlying Windows operating system build. For example, Windows 11 version 26H2 uses the base OS build 26300.
Build Revision
The build revision identifies subsequent servicing changes delivered through Windows updates.
For example, 26300.9818 consists of:
- 26300 – Base OS build number.
- 9818 – Update revision number.
This is why your Windows 11 build number may change after installing a cumulative update, even though the feature version remains unchanged.
