Microsoft has recently released new Insider builds for Windows 11, targeting testers in the Dev and Beta channels. One notable feature in these builds is the Windows 365 Switch, which allows users to effortlessly switch between their local desktop and a Windows 365 Cloud PC. Additionally, a new build has been made available for the Release Preview channel, incorporating app default changes that have previously been tested on other Insider channels.

For the Dev Channel, build 23521 brings back the Windows Copilot preview for users logged in with an Azure AD account. Furthermore, Microsoft is introducing new privacy settings for Windows users in the EU. Here are the key changes in this build:

1. Windows 365 Switch: Windows Insiders now have the capability to seamlessly switch between their local desktop and a Windows 365 Cloud PC through Task View.
2. Windows Copilot on managed PCs: Insiders logged in with an Azure AD account can once again access Windows Copilot.
3. Taskbar never combined mode settings: The settings app now provides more detailed options for enabling never combined mode on the taskbar. There is now a separate setting for enabling this mode in scenarios involving multiple monitors.

8. Pin widgets board open: A new pin icon has been added at the top of the widgets board, allowing users to keep it open at all times.
9. Snipping tool changes: The app now provides new shortcuts for editing screenshots in Paint and screen recordings in Clipchamp.

As for the Release Preview Channel, build 22621.2213 encompasses the following main changes that will eventually be included in the next month’s Patch Tuesday update for Windows 11 version 22H2:

1. Changes for app defaults: Apps can now use a deep link URI to directly navigate users to the corresponding location in Settings in order to change their default app.
