新機能

What's new for Windows 10, version 21H1, Windows 10, version 20H2, and Windows 10, version 2004 release notes

Windows 10, versions 21H1, 20H2, and 2004 share a common core operating system and an identical set of system files. As a result, the release notes for Windows 10, versions 21H1, 20H2, and 2004 will share an update history page. Each release page will contain a list of addressed issues for 21H1, 20H2, and 2004 versions. Note that the 21H1 and 20H2 versions will always contain the fixes for 2004; however, 2004 will not contain the fixes for 21H1 and 20H2. The update history page will provide you with the build numbers for 21H1, 20H2, and 2004 versions so that it will be easier for support to assist you if you encounter issues.
