New features and changes[edit | edit source]

Suggested actions[edit | edit source]

The ability to show up a pop-up offering to search the copied text with search potential in Microsoft Edge, initially introduced in build 25247, has been removed.

File Explorer[edit | edit source]

A new folder named Gallery (GUID {E88865EA-0E1C-4E20-9AA6-EDCD0212C87C}) has been added in the navigation pane. Opening it will be redirected to the Pictures folder, although it's impossible to cut, copy and paste files within it or view its properties. This change is disabled by default, but can be toggled on manually by enabling the 41040327 and 42295138 velocity IDs.

  • Task Manager will inform users explicitly if there are no matching search results.

Settings[edit | edit source]

Widgets[edit | edit source]

  • On right-to-left locales, the content may animate out of view before the Widgets board resizes when clicking to expanded view of the Widgets board.

Safe mode[edit | edit source]

  • Enabling the search box/icon on the taskbar may cause explorer.exe to hang or crash.
  • 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.

Hidden velocity IDs[1][2][edit | edit source]

Some IDs are work-in-progress, so it might not work as expected

Starting with this build, several velocity IDs related to a major File Explorer update has been added. It is possible that Microsoft is preparing a big File Explorer revamp for later versions.

  • 38613007 (FileExplorerInsights) — Insights feature, responsible with the new File Explorer details pane (works in build 25276 and onwards, backported and refined in build 23430)[3][4]
  • 38664959 (FERecommendations) and 40064642 (FERecommendationsUdk) — Recommendations in File Explorer (works in build 25314 and onwards, backported to build 23430)[a][b][5]
  • 39661369 (FETTOM) — the ability to drag a File Explorer tab out to create a new window (usable in build 25290)
  • 40950262 (FEMNB) — new navigation bar and relocated command bar buttons (works in build 23466.1001)[6]
  • 41040327 (FileExplorerGallery) — Gallery feature (works in this build, refined in build 25300 and build 23430)[7][8]
  • 41076133 (XAMLFEHome) — new File Explorer home page, which features new animations and shows recommendations in larger titles (works in build 23419 and onwards, later added in build 25330).[9][10]
  • 42295138 (XAMLFolderViewSupport) — XAML folder viewing in File Explorer support.[c]

There are 2 velocity IDs that have FE on its name, so they are likely a part of this File Explorer update, but they can't be predicted at the moment (as of 2024):


  • 41360093 (FEBIT)
  • 42052883 (FEODW)

Notes[edit | edit source]

  1. ↑ This feature can be toggled on or off via the Folder Options applet, but currently it does not show due to being disabled
  2. ↑ Only works for Azure Active Directory-signed account, but support for other types of accounts may get added soon.
  3. ↑ This is a prerequisite of the new "Gallery" feature and required this ID to be enabled in order for the feature to work
