My main machine runs WIN 7 Professional 64 bit. A couple of years ago, a 'free' WIN 10 upgrade appeared in my updates and urged me to "upgrade" to WIN 10 for "free". It was unable to do that, however, and after 20 attempts, I quit. I continued along as usual, then noticed my antivirus and my system cleanup programs were no longer able to function due to a burning necessity to restart so WIN 10 could "finish installing". It couldn't do that, of course, which leaves me with an ever - increasing amount of crap/trash (file butts & fragments etc) and a concern that I may pick something up on the interwebs and not be able to remove it due to the (now infamous) WIN 10 install lockup. I am also unable to download any other updates as well, until I can get that nasty brick from out my updates application. Please Register or Log in to view the hidden image! I Googled for a fix and have found several. None of those worked. Neglecting that Microsoft (one of the Great Evils) has deliberately infected my system with what acts like a virus and has screwed up my machine, do any of us here have a serious method to get rid of this lockup without destroying everything I have on this computer? This includes programs that were downloaded, so I can't just pop the disc back in and reinstall, so if I reinstall WIN 7 over this mess, I lose everything. I believe this is the same thing that will happen if I go ahead and buy WIN 10 and install that POS over everything. So does anyone have a plan that will actually work to remove this lockup without destroying my system?
