Microsoft released the first Windows 11 Insider Preview in 2022, Windows 11 Build 22526 in the Dev channel. The changes and improvements of Windows 11 Build 22526 are as follows:
- Windows 11 Build 22526 displays ALT + TAB as a window, no longer the full screen.
- Windows 11 Build 22526 supports wideband voice and improves the audio quality of voice calls when using Apple AirPods products, including AirPods, AirPods Pro, or AirPods Max.
- From Build 22518, Credential Guard is enabled by default on Windows 11 Enterprise (E3 and E5) licensed PCs that join the enterprise.
- Windows 11 Build 22526 attempts to index more file locations so that you can use search in File Explorer to find important files faster.
ALT + TAB being windowed instead of full screen is undoubtedly a huge visual behavior change. However, it only applies to users who join the Dev channel to try the features. The other changes, such as broadband voice for AirPods, are available to all Windows 11 users.

Like the previous version, Windows 11 Build 22526 has made some fixes and some known issues:
