The thread may still end up going further up the chain and to the protected board, but time will tell.
It may be a case, I have only had one system like this (and it was Windows 7) whete what ever caused it has blocked use of files ot settings so that the likes of System Restore can't be used, makes Windows think files are missing, and so programs and Windows functions won't run properly.
