I have multiple computers on an intranet getting Windows Update via WSUS. Since last year, I have one particular computer running Windows 10 (OS Build 19041.1110) that has been failing to install Windows Update KB5006670 with error 0x8024200d and 0x8024200b. Now that Windows 10 version 2004 is end of life, I attempt to bypass this problem by upgrading it to Windows 10 version 21H2; however, to upgrade it to version 21H2, I need to install KB5005565. Sadly, I got a different error now (0x80073712).
I ran SFC /SCANNOW which I found unrepairable corrupted file relating to pwrshmsg.dll.mui, but I was able to resolve that issue by running DISM /Online /Cleanup-Image /RestoreHealth. Now that both commands are showing no issue, I am still stuck on how I can resolve this error 0x80073712 especially after installing the update manually instead of via WSUS.
