Hi, I recently had a rather stupid idea, I had a patched copy of ms windows 7 pro working correctly on my laptop. Then I got the urge to install the windows 10 technical preview on that laptop..of course it didn't install correctly, and when I 'rolled back' to what was installed windows 7 pro, I had to make it 'genuine' once again. Now when I try and download/install windows updates, it opens and acts like it's searching for updates..but never finds any. I'm informed that there aren't any updates. I have a shortcut on my desktop to windows update, but on that desktop icon, there's a padlock. I have tried to repair windows update..but can't seem to work correctly. Any ideas ?? Thanks, David
