New features and changes[edit | edit source]

Shell[edit | edit source]

  • The new experimental search box on the desktop, which initially introduced in build 25120, has been disabled by default. However, this feature is still present and can be enabled by using ViveTool from an elevated Command Prompt window to enable the 37969115 velocity ID.
  • The Search entry point on the taskbar has been redesigned with five variants. This feature is only available to a subset of users, and its design may vary between devices. To enable it, use ViveTool from an elevated Command Prompt window to enable the 39072097 velocity ID with variant parameters between 1 and 5.

File Explorer[edit | edit source]

  • The folder name will be always visible in the tab at the top of File Explorer when the "Show full path in title" option is enabled.
