he updates for my Server 2019 machine continue to fail with the following errors: 2021-03 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB5000822) - Error 0x800703f1 Security Update for Windows Server 2019 for x64-based Systems (KB4535680) - Error 0x8007371c The Cumulative Update has been failing since 2021-01, I have not found solutions specific to Server 2019 so I have tried the following techniques discussed for Windows 10; none of them have worked. 1. Running the Windows Update troubleshooter. 2. Resetting Windows Update components manually using the following commands: net stop wuauserv net stop cryptSvc net stop bits net stop msiserver Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old Ren C:\Windows\System32\catroot2 Catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver 3. Running DISM.exe /Online /Cleanup-image /Restorehealth 4. Running sfc /scannow 5. Downloading (and installing) the most recent Servicing Stack Update (SSU) 6. Downloading (and installing) KB5000822; install failed. Reinstalling the OS is not an option at this point. I've burned a lot of time on this so any help will be greatly appreciated. Thanks! Ken
