And the update: Sis's laptop seems to be fine now. Some settings seem to be working properly now (though that was done after DISM and SFC twice).

Originally, the unit BSODed, then it was brought to me. Unit also had a delay powering on, then it started checking the disk for errors. Then it booted to the Windows desktop.

Then part of the AMD GPU drivers were corrupt. This prompted me to scan the disk twice: /f, then /r. Noticed the Date/Time Settings would crash, but pretty much everything else was fine.

Sadly, DISM was pretty much useless, but sfc /scannow was not so. This was run twice. Eventually, the Date/Time Settings worked.

Also noticed after DISM, the build number discrepancy showed.
