a couple of months ago the updates started to fail. at the time i ran a system restore but it never allowed one update to take. now all updates fail. this is a second machine but still useful. i cannot locate the original restore discs, if they have any use. i'm not sure how to go about recovering. even windows 10 needs a special app that won't install.
you guys helped this machine before with a malware infection, what do i do now?
You can try Windows 10 but I strongly urge you to do a image backup to an external hard drive first. That way if something goes wrong you can get back to where you are now in about 20 minutes. If you don't have one, get one. You can get a 1TB external USB 3.0 driver for $50 to $60.
