If you're using Driver Sweeper to clean up drivers on Windows 7, be aware that Driver Sweeper may prevent you from installing service packs. Driver Sweeper wipes Windows 7's built-in display drivers, which are considered as "system files". Service pack 1 and upcoming service packs run integrity check on system files, and if it detects any missing files – it won't let you install and display the following error message: Service Pack Installation Cannot Continue (one or more system components that service pack requires are missing).
