KB5040525 update for Windows 10 is only available for 22H2 PCs and focuses on fixes rather than adding new features. The update resolves issues such as Windows Defender Application Control breakdown, Print Support app not responding, Universal Print clients failing to work with the Universal Print service, and Windows Backup app failing with an EFI system partition. The update also fixes the DHCP Option 235 problem that has been present since January 2024. The profile picture bug with error code 0x80070520 persists, with the Settings app wrongly displaying the error code while changing the profile picture.
