New features and changes[edit | edit source]

Widgets[edit | edit source]

The following features have been introduced to a subset of users:

  • The expanded view of the Widgets board, which is accessible via the new Expand/Collapse button in the top right corner of the board, next to the Add widgets button. This feature can be toggled on manually by enabling the 34300186 velocity ID and restarting Widgets.exe.
  • The support for signing in to the Game Pass widget using an Xbox account. Once signed-in, the widget will show the available Game Pass games as well as a list of the most recently played games.

File Explorer[edit | edit source]

  • The default folders unpinned to the navigation pane will be re-pinned after upgrading to this build.
  • Several cloud files have been added to search results from the Home page.
  • The ability to populate full search results while typing, previously removed in Windows 10 build 18894, has been re-introduced. As part of this change, the default size of the search box has also been reduced. This feature is only available to a subset of users, but can be toggled on manually by enabling the 38665217 velocity ID.

Shell[edit | edit source]

  • The redesigned Search box in the taskbar, initially introduced in build 25158, has been disabled by default. This feature can still be toggled on by enabling the 39072097 velocity ID with the variant number set to between 1 and 6.
  • The new wording on Start menu's search box, initially introduced in build 25197, has been rolled out to more users.

Settings[edit | edit source]

Several UI elements have been redesigned in order to align the design aesthetics of Windows 11:

  • The "Change date and time" dialog (available under the Date & time page if the "Set time automatically" option is disabled), which can be toggled on manually by enabling the 36390579 and 39811196 velocity IDs.

Settings[edit | edit source]

Virtualization[edit | edit source]

  • Users may experience a UNSUPPORTED_PROCESSOR bugcheck when booting Windows in VMware on a Hyper-V enabled host with 2 or more cores allocated.
  • The system may fail to boot in VMware with attached network adapters.

Widgets[edit | edit source]

Safe mode[edit | edit source]

  • Quick Settings and date/time clock on the taskbar may be missing due to the Capability Access Manager Service service not running.
  • Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer 0xc0000409.
