You can often repair software problems by completing a System Restore in Windows 7. Windows 7 is much less buggy than Windows Vista, but sometimes bugs in software and driver updates will cause your system problems. These system errors can include everything from the system running slowly to the system coming to a screeching stop.
If you start to notice these kinds of problems, you’ll want to manually restore your computer back to the way things were running before the recent software or driver update. In other words, to the way it was before the problems began.
Save your work and then close all running programs.
Although System Restore doesn’t bother your data files, it can mess up settings. It’s safest to just close everything.
Choose Start→All Programs→Accessories→System Tools→System Restore.
