I want to repair Windows 7 Home Edition 64 bit - as I have problems with Restore and two new Windows updates won't install - error 80070490. I've tried everything to fix this to no avail. Microsoft have just removed the downloads from Digital River and will not let you have the ISO with a factory OEM disc. This is ridiculous as it is a legitimate copy. I found a download but I think it is an old one - X15 65733. I hope this hasn't got a virus - if it hasn't, will it work. It would appear the latest ISO starts with X17. Any suggestions for me at all please?
