How to reboot my laptop back to factory settings
Rebooting your laptop back to its factory settings restores your computer and its hardware to its original settings when it was purchased. This is helpful when troubleshooting major hardware and system performance issues. It can also be used to fix virus related issues. Restoring your computer to its factory settings is similar to performing a clean install of your operating system. Windows uses a utility program called System Restore that allows you to restore your computers settings to a specific date.
Turn on your computer, and then click on the "Start" menu icon in the bottom left-hand corner of the screen. Select "All Programs," and then click on the "Accessories" drop-down menu.
Scroll down to "System Tools," and then select the "System Restore" program and wait for it to open.
Select the "Restore My Computer to an Earlier Time" option, and then click on the "Next" button to continue. A window with a calendar will appear.
Click on the back arrow in the calendar's window. Click on the back-arrow until you have reached the date you either purchased or installed Windows on your laptop. Select the appropriate date, and then click on the "Next" button to continue. Your computer will automatically restart.
