Started with SFC /scannow and DISM online with basic start of repairhealth and both for most part fail or had failed. I've gotten to the point of where I have been trying to run DISM using an ISO, mounted ISO drive path, and also a restored local copy of the C:\Windows folder from backup, to point to as a source. But consistently fails indicating it can't see/find the source. (even though am explicitly pointing it to valid sources). Consistently appear to be getting 800F081F as error.
