Hello Quite frankly I find the microsoft updates to be a pain in the backside. You really do not need most of them anyway. They can cause more problems than they solve. I have them turned off all the time. They also take up valuable space on your hard drive. Believe me I have had a pc for the last eleven years and I was told by someone in the know that updates are a waste of time. Have not used them for last five years and pc is fine. The last big vunerability I had a message for was with using MS Explorer, so I swapped to Fire fox Mozilla. Ten times better and much faster. Most of the vunerabilities that they find are to do with buisiness computers. As for your cured problem you may at some point have deleted something that has allowed it to update. Some viruses can block updates so maybe a scan has cleared the problem. Hope this helps. Mick.
