Here's what you need to do:
If you're a Windows Vista or Windows 7 user, click Start, type Windows Update, and then hit Enter. (XP users should head to the Control Panel and seek out Windows Update.)
Click the Change Settings option at left. (That's where it appears in Vista and 7; not entirely sure about XP.)
Change the setting to Download updates but let me choose whether to install them.
If the issue is still not fixed, it can be a very critical problem with your computer affecting your personal data and the Windows Operating System. You will have to chat with our Experts or you can check with your local technician to get the problems fixed with very high priority.
