The quickest way to restart your PC

The fastest restart is through the Start menu. Click the Windows logo in the bottom left corner of your screen, then click the power icon (a circle) in the bottom right of the menu that opens. Select Restart from the options shown. Your PC will close all open programs and restart within seconds.

This method works on Windows 10 and Windows 11. If you have unsaved work, Windows will prompt you to save it before restarting. If you ignore the prompt and restart anyway, you will lose that work.

Key Takeaways

  • The Start menu power button is the fastest way to restart—click the Windows logo, then the power icon, then Restart.
  • A keyboard shortcut (Alt + F4, then selecting Restart) works if your mouse is not responding or the Start menu is frozen.
  • The Command Prompt method gives you a 30-second countdown before restart, so you have time to save work if needed.
  • Always close or save your programs before restarting, because unsaved files will be lost when the PC shuts down.

Using the keyboard shortcut when your mouse does not work

If your mouse is frozen or not responding, use your keyboard instead. Press Alt + F4 to close the active window. If no window is open, this will open the shutdown menu. Use the arrow keys to highlight Restart, then press Enter.

This method bypasses the Start menu entirely and works even when your mouse is completely unresponsive. The restart will begin when ready after you press Enter, so make sure any work you need to save is already saved before you use this shortcut.

Restarting from Command Prompt with a countdown timer

Command Prompt gives you a 30-second warning before the restart begins, which is useful if you need time to save work. Press Windows key + R to open the Run dialog. Type cmd and press Enter. In the black Command Prompt window, type shutdown /r /t 30 and press Enter.

Your screen will display a message saying "The system is shutting down" with a countdown timer. You can cancel the restart by typing shutdown /a in Command Prompt before the timer reaches zero. This method is helpful when you want to restart but need a few moments to close programs or save files.

What happens during a restart

When you restart your PC, Windows closes all open programs, saves system settings, and shuts down completely. The PC then powers back on and loads Windows fresh. This process usually takes 30 seconds to two minutes, depending on how many programs you have installed and how fast your hard drive is.

During a restart, any files you had open but did not save will be lost. Windows will not restart until you close programs that have unsaved work, or you can force the restart anyway and lose that work. If a program is frozen and will not close, restarting is often the fastest way to fix it.

When to restart instead of shut down

Restart your PC when a program is frozen, when Windows is running slowly, or when you have installed updates that require a restart. Restarting clears your computer's memory and stops all background processes, which often fixes performance problems. Shut down your PC when you are done using it for the day and want to save power.

A restart is faster than shutting down and then turning the PC back on, because it skips the full power-down cycle. If Windows is behaving strangely or a program keeps crashing, restart before trying anything else—it solves most temporary problems.

Troubleshooting a restart that will not complete

If your PC is stuck on the restart screen or the restart is taking longer than five minutes, hold down the power button on the front of your PC for 10 seconds until it shuts off completely. Wait 30 seconds, then press the power button once to turn it back on. This is called a hard restart and forces the PC to shut down without the normal shutdown process.

A hard restart can occasionally cause problems with files or programs, so use it only when the normal restart is frozen. After a hard restart, Windows may run a disk check the next time it starts up—let it finish, even if it takes several minutes. If your PC keeps getting stuck during restart, you may have a hardware problem and should contact a technician.

Restarting after a Windows update

Windows updates often require a restart to finish installing. When an update is ready, Windows will show a notification asking you to restart. You can choose to restart right away or delay the restart for a few hours. If you delay too long, Windows will restart automatically at a time when you are not using the PC.

Before restarting after an update, close any programs you are using and save your work. The restart will take longer than usual because Windows is finishing the update installation. Do not turn off your PC during this process, or the update may not complete correctly and your PC could have problems starting up.

Frequently Asked Questions

Will restarting my PC delete my files?

No. Restarting will not delete any files saved on your hard drive. It only closes programs that are currently running. Any files you created and saved before the restart will still be there when your PC starts back up.

How long does a restart usually take?

A normal restart takes 30 seconds to two minutes from the moment you select Restart until Windows is fully loaded and ready to use. Older PCs or PCs with many programs installed may take longer. After a Windows update, the restart can take five to ten minutes.

Can I restart my PC while it is updating?

No. If Windows is in the middle of an update, you should not restart or shut down your PC. Wait for the update to finish, then restart if prompted. Interrupting an update by restarting can damage Windows and make your PC unable to start.

What is the difference between restart and shut down?

Shut down turns your PC off completely and stops all power. Restart shuts down and then when ready powers back on. Restart is faster if you want to use your PC again soon, and it clears memory better than just closing programs.

Why is my PC slow after restart?

Your PC may be slow right after restart because Windows is still loading programs and services in the background. Wait two to three minutes before opening programs. If your PC is still slow after that, you may have too many programs set to start automatically when Windows loads.
