Repairing Software Problems Your computer uses the operating system and installed software programs during normal operation. If your computer works improperly or stops, you may be able to repair it. Restarting Your Computer Restarting is the simplest repair method for your computer. When you restart, the computer reloads the operating system and software into its memory. To restart your computer: 1 Close all open programs and windows. 2 Click the Windows Start Button, click the Arrow button next to the Lock button, and then click Restart. Turning Off Your Computer When you turn off your computer and then turn it on again, you force the computer to reload the operating system into its memory, which clears some tracking information. This may eliminate some problems that can remain after you perform a restart. To turn off your computer: 1 Close all open programs and windows. 2 Click the Windows Start Button, click the Arrow button next to the Lock button, and then click Shut Down. 3 Start your computer by pressing the On button.
