No problem! So after DISM was healthy, SFC was able to fix corruption and I was able to re-add the XPS features with the spooler service stopped.
However, I still am not able to add the XPS Document Writer. When adding the printer manually it says "Element not found".
I totally understand if this is now outside the scope of this forum but if not, I could use some direction.
Comparing to the DISM source server I used earlier, I see that one file in this folder is different:
C:\Windows\System32\DriverStore\FileRepository\prnms001.inf_amd64_f340cb58fcd23202\
It's the prnms001.pnf file. Would this not be resolved by running DISM/SFC?
Thanks,
Dan
