really stumped here. Usually if sfc fails to repair corruptions, then i run a dism online restore health cmd followed by sfc and that is that. but in this bizarre case a domain user reported his screen was flashing, so i immediately scanned for malware with bitdefender and came up clean. then, i logged on with another domain user account and things looked good. loggin back on with the original domain user resulted in his desktop flashing again. so i deleted his profile from a domain admin account on that pc. had him log in again, and the problem was still there. ran sfc and discovered corruptions that it could not repair. ran dism and it failed with dism error 193. downloaded the win10 media creation tool and tried an in place upgrade and it failed. pulled the pc off the domain and tried again. same results with sfc and dism. tried using sfcfix and it crashes. Any ideas out there? I will post a couple of logs here.
