I got a free upgrade for windows 10 through windows 7 ultimate from using assistive technologies. Since then my computer has been freezing any time i try to load a game or install anything. I try to run disk cleanup and the computer always seems to freeze on previous windows installion and the windows.old file. Ive updated drivers, reinstalled windows, reset winsock catalog, ran sfc scan, almost anything you can think of. I really like windows 10 and would like to keep it. The freezing is the only issue I have.
