Back up all your data, to a disk or cloud, then just reinstall a clean copy of the OS and restore.
Be careful with that. I have the install disks for my computer, but it won't matter. Microsoft shut off software updates. I had a SSD partly crap out, went back to a previous bootable drive. Can't update browsers, OS, a whole pile of things. Best is to have a separate drive for data as for OS and keep a rotating full bit-copy. I should have been doing that after every Windows update that was successful. Live and learn.
