Hi Guys If anyone knows of a solution on fixing my problem I would be most grateful. The problem is I have missing and possibly not quite sure corrupted files in Windows 8.1 OS. I have tried to do a System Restore, no good. Also have used Reimage software and Tweaking Windows.com without any success. Does anyone know of a solution to repairing or replacing files without having to Reformat and loosing everything. I have tried Windows PC Refresh. It doesn't work it asks me to install Media disc in to PC. which from then on I will lose everything. Any miracle thoughts guys Ta. PS System is clean no Viruses.
