Laptop performance can decrease over time due to software errors, unwanted programs and old files. You can restore a laptop to factory settings, with or without restore disks, to improve performance and efficiency. Because operating system versions differ among laptops, please refer to product documentation for the exact restore procedure for your laptop. Be sure to back up all of your data somewhere other than your laptop before restoring it back to the factory settings, because restoration will reformat your hard drive, erasing all previous memory.
