I just got a used laptop, popped in a new hard drive, and installed a legit version of Windows 7 Ultimate from scratch. Everything went smoothly, it picked up on all my devices & installed drivers correctly. The only problem is - I can't update Windows. When I go to start--> all programs--> windows update, it goes to "checking for updates" and does that - forever and ever - even if I leave it go overnight. I did a google search, and found many people having the same problems. There were instructions to follow to solve, but nothing solved mine. Can anyone please help?
