Windows Server unable to install Cumulative update 21H2 for x64-based Systems (KB5066782)
Hi All,
Unable to install the above update. I tried things like sfc/scan, dism tool features but non works. all other updates install except the above. Tried running the update manually but failed. Think this is also breaking functionality of the virus /malware guard. ACS (azure Code signing). The last option that I am thinking of is to run a sever repair with the installation media. I also tried windows trouble-shooter for updates.
Any ideas ?
This is installed as a virtual machine on Hyper-V. Don't want to rebuild the server. Looking for a solution.
The Error code is
- 0x80073701

Do an in-place update leaving files in place. That fixed whatever was broken.
To enter recovery boot
reagentc /boottore
shutdown /r /t 0
From the recovery boot command line
dism.exe /image:C:\ /cleanup-image /revertpendingactions
I have the same issue - Windows Server 2022. Have tried multiple times including manual update. No dice. Also on a Hyper-V virtual machine.
Same thing here as well. But I'm hosted in Azure. tried everything but still fails.
