You attempt to update your video driver. Your screen stops responding. You need to be able to restore the previous video driver. Which Windows feature should you use?

Disk Defragmenter optimizes hard drive performance by reorganizing fragmented files, which is unrelated to driver issues.

Disk Cleanup removes unnecessary files to free up disk space and is not used for driver recovery.

Check Disk (Chkdsk) scans the hard drive for file system errors and bad sectors, which does not help with a problematic video driver.

Safe Mode starts Windows with a minimal set of drivers and services, which often allows the operating system to boot even when a problematic driver prevents normal startup. Once in Safe Mode, you can access Device Manager to roll back the video driver to its previous version, resolving the display issue.
