Since Win10 tried to unsuccessfully load, I've have "virus-type" issues. Explorer won't open when clicking on the advanced system settings or properties. I found that there is a conflict with WinSAT, which I renamed in order to FIANLLY be able to use the restore feature only to find it had been turned off. I renamed both WinSAT.exe and Winatapi.dll to .old files. It worked to allow me access, but I fear it's only temporary workaround. MMC hasn't functioned - it comes up with a snap-in error. Ever heard of this? I'm presently backing up my system which has taken 11 hours so far to get about 40% of it backed up, including an image as per the windows repair/restore steps. My DVD player wiped out, so I couldn't load from it. I just replaced it, only to find the computer could not detect it on start-up....ANY HELP!?!
