To reboot a computer, hold down the “Ctrl”, “Alt” and “Del” keys at the same time, and then release the keys. Depending on the operating system that the computer is running, the computer either reboots immediately or shows a lock screen with the option to restart the system.
To reboot a computer running Windows Vista, Windows 7 or Windows 8, click the Start orb that is located in the lower-left side of the screen. Next, click the right arrow shown next to Shut Down, and then select Restart. The reboot option is found under Power on the Start Menu in Windows 10.
Rebooting a computer fixes many slowdowns and errors; however, it does not restore the computer to its factory default state. To reset a computer that has serious software errors, use the recovery option. On Windows 10, the recovery option is located under the Settings option on the Start Menu. Select Update & Security, and then click on the Get Started option underneath Reset this PC. Using this feature restores Windows back to its original state but offers the user the option to keep documents. Note that any third party software needs to be reinstalled once the reset has completed.
