Same issue with "2025-01 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5050009)", it is not installing and still asking for restart but after restart still the same, not update.
Also manually run the update but still having the same massage, restart required..!
Already run the SFC Scan for corrupted files but all was OK "Windows Resource Protection did not find any integrity violations"
I'm running Win 11 version 24H2 (OS Build 26100.2894) on Dell Latitude 7390
Any feedback on this?
