I don't know what has happened fully to this server, but it won't run updates, manual updating .NET 4.7.0 to 4.8 fails.
SFC and DISM won't work either:
sfc /scannow
Windows Resource Protection could not start the repair service.
Dism /Online /Cleanup-Image /RestoreHealth
Deployment Image Servicing and Management tool
Version: 10.0.14393.4169
Error: 1812
An initialization error occurred.
For more information, review the log file.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
I believe someone tried to copy WINSXS from a working PC, complicating things further. Any help is appreciated.
