We have a windows 2019 server which is unable to install any windows update.
The reported error is the following for all the patches
Windows update "Update for Windows (KB5022554)" could not be installed because of error 2147943409 "The configuration registry database is corrupt." (Command line: ""C:\Windows\system32\wusa.exe" "C:\Users\xxx.root\Downloads\windows10.0-kb5022554-x64_a4abb49dda1c095d655f6161616e11a2f9705afa.msu" ")
we've already tried all the KB found so far about using DISM /healthcheck ..
also tried SFC /scannow.
so far non worked
Has anyone any other advice ?
thanks
