Bugs and quirks[edit | edit source]

Shell[edit | edit source]

Some non-system apps under Start menu's All Apps section, such as PWA apps installed via Microsoft Edge, may be labeled as system apps incorrectly.

Windows Copilot[edit | edit source]

  • When pressing Alt+Tab ↹ to switch out of Windows Copilot, users may not switch back into it.
  • When first launching or after refreshing Windows Copilot while using Voice access, users may need to use "Show grid" commands to click in the "Ask me anything" box for the first time.
  • Copilot isn't available in most regions for an unknown reason.

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.
