Bugs and quirks[edit | edit source]

This build is incorrectly labeled as "Windows 11" in Windows Update.
A blank option may appear on the Privacy & security page in the Settings app, where if clicked on it would crash the Settings app with the 0xc000027b exception code.
Archiving eventlogs with wevtutil al command may cause the Windows Event Log service to crash, and the archive operation to fail.
Upgrading to this build from Windows Server 2019 or Windows Server 2022 may fail with several intermittent upgrade failures.
Upgrading to this build on devices with System Guard Secure Launch/DRTM code path enabled may fail due to unknown reasons.
