A new preview of Windows 11 bundles the PC Manager app for users in China.

  • Windows 11 build 22635.3646 (KB5037858) rolls out fixes for File Explorer as well as for printers, networking, drivers, and more. However, this update doesn’t introduce new features or significant changes.

Microsoft has released the preview build 22635.3646 (KB5037858) for Windows 11 in the Beta Channel of the Windows Insider Program. The update is minor but introduces several fixes, improvements, and changes for existing features.

According to the official notes, Windows 11 build 22635.3646 fixes a couple of problems with File Explorer and addresses problems with printers, out-of-the-box experience (OOBE), networking, Share experience, and more.

Furthermore, this update also installs the “PC Manager” app for users in China. PC Manager is an app with different tools to improve your device’s performance, security, and overall health. However, the app doesn’t introduce new features besides the “PC boost” option. Instead, it’s a collection of tools already available on the system.

In addition to build 22635.3646, the company has also made available build 26100.712 in the Release Preview Channel as the first preview for version 24H2, which ships with several new features, such as Sudo for Windows, Energy Saver, archival creation wizard from File Explorer, changes for Quick Settings, a new Copilot app, and more.
