The fastest way to restart Windows 11

The quickest restart on Windows 11 is the keyboard shortcut: press Windows key + X, then press U, then press R. Your computer will restart in about 15 seconds. This works from the desktop, from inside any program, and even if your mouse stops responding.

If you prefer not to use keyboard shortcuts, the Start menu method takes about 20 seconds. Click the Start button (bottom left), click the power icon (bottom right of the menu), and select Restart. Windows will close all open programs and restart.

Both methods do the same thing: they shut down Windows completely and boot it back up. The difference is only in how many clicks or key presses you use to get there.

Key Takeaways

  • Windows key + X, then U, then R is the fastest restart method and works even when your mouse is not responding.
  • The Start menu method (Start button > Power icon > Restart) takes slightly longer but requires no keyboard shortcuts.
  • A restart closes all open programs, so save your work before you begin.
  • If your computer is frozen and will not respond to keyboard or mouse, hold the power button for 10 seconds to force a shutdown, then press it again to turn it back on.

Using the Start menu to restart

Open the Start menu by clicking the Windows logo in the bottom left corner of your screen. The Start menu will slide in from the left side.

Look for the power icon in the bottom right corner of the Start menu — it looks like a circle with a line at the top. Click it once. A small menu will appear with three options: Sleep, Restart, and Shut down. Click Restart.

Windows will display a message saying your computer will restart in about one minute. Save any open work before this countdown ends. When the timer reaches zero, Windows closes all programs and restarts automatically.

Restarting from the Settings app

Open Settings by pressing Windows key + I. The Settings window will open on the right side of your screen.

On the left side of Settings, click System. Then on the right side, scroll down and click Recovery. You will see a button labeled Restart now under the "Recovery options" section. Click it.

This method is less common than the Start menu or keyboard shortcut, but it works the same way. Use it if you are already in Settings and want to restart without navigating back to the Start menu.

Force restart when your computer is frozen

If your keyboard and mouse do not respond, your computer may be frozen. Do not unplug it or remove the battery — a forced shutdown can damage files. Instead, hold down the physical power button on your computer for 10 full seconds. The screen will go black and your computer will shut down completely.

Wait 30 seconds, then press the power button once to turn it back on. Windows will restart normally. When it boots up, you may see a message asking if you want to start in Safe Mode — you can click No, start Windows normally to continue as usual.

After a forced shutdown, Windows may run a disk check the next time it starts. This is normal and takes a few minutes. Do not turn off your computer during this check.

What happens during a restart

When you restart, Windows closes every open program without saving unsaved work. Before you restart, save any documents, spreadsheets, emails, or other files you are working on. If a program asks "Do you want to save changes?" when it closes, that means you have unsaved work.

A restart is different from Sleep mode. Sleep keeps your programs open in memory and wakes up in seconds. A restart shuts everything down and boots Windows fresh, which takes 30 seconds to two minutes depending on your hardware and how many programs you have installed.

Restarting can fix many common problems: programs that freeze, internet that stops working, or your computer running slowly. It clears temporary files from memory and gives Windows a fresh start.

Scheduling a restart for later

If you want your computer to restart at a specific time rather than right now, you can schedule it using the Command Prompt. Press Windows key + R to open the Run dialog, type cmd, and press Enter.

In the Command Prompt window, type this command: shutdown /r /t 3600 (the 3600 is the number of seconds to wait — 3600 seconds equals one hour). Press Enter. Your computer will restart in one hour and display a countdown warning.

To cancel a scheduled restart before it happens, open Command Prompt again and type shutdown /a, then press Enter. The restart will be cancelled.

Restarting in Safe Mode

Safe Mode starts Windows with only the most basic drivers and programs. Use it when you suspect a recently installed program is causing problems. To restart in Safe Mode, press Windows key + X, then press U, then press U again (instead of R). Your computer will restart and show a menu with boot options.

Select Safe Mode from the list. Windows will start with a black background and fewer features than normal. You can uninstall a problem program, run antivirus software, or troubleshoot other issues. When you are done, restart normally using any of the methods above.

Frequently Asked Questions

Will restarting delete my files?

No. A restart shuts down Windows and boots it back up, but all your files stay on your hard drive. Only unsaved work in open programs will be lost — that is why you should save before restarting.

How long does a restart take?

A typical restart takes 30 seconds to two minutes from the moment you click Restart until Windows is fully loaded and ready to use. Older computers or computers with many programs installed may take longer.

What is the difference between restart, sleep, and shut down?

Restart closes everything and boots Windows fresh. Sleep puts your computer in a low-power state and wakes in seconds with everything still open. Shut down closes everything and turns the computer completely off — you must press the power button to turn it back on.

Can I restart my computer remotely?

Yes, if you have Remote Desktop or another remote access tool set up. You can also use the Command Prompt method on another computer if you have network access to the target computer. For most users, restarting locally using one of the methods above is simpler.

Why does my computer restart on its own?

Windows may restart automatically after installing updates, or a program may be set to restart your computer at a scheduled time. Check Settings > System > About to see if updates are pending. You can also check Task Scheduler to see if any tasks are scheduled to restart your computer.
