Several weeks back, Microsoft rolled out KB5037769, a patch delivering key security enhancements for Windows 11 systems. Regrettably, this release has sparked difficulties for certain users, including BitLocker access denials, sudden restart cycles, and glitches in Remote Desktop functionality.
As May arrives, the troubles persist. Reports indicate that the KB5037769 patch is interfering with numerous third-party backup solutions, such as Acronis Cyber Protect Cloud, Macrium Reflect, NinjaOne Backup, and UrBackup Server.
These disruptions seem to originate from a flaw in the Volume Shadow Copy Service (VSS), which is a built-in Windows feature responsible for generating file snapshots at specific moments to enable backups without interrupting operations.
BleepingComputer reports that affected individuals should remove the KB5037769 update to restore functionality to their backup applications. No timeline has been announced regarding Microsoft's plans to resolve the problem through an upcoming fix.
