How to Restart Windows: 4 Simple Ways

Restarting Windows clears temporary glitches, applies updates, and frees up memory that has been consumed by background processes. This guide covers the standard methods for restarting a Windows 10 or Windows 11 PC, including what to do when the usual Start menu option is missing or the system is frozen.

What You’ll Need

• A Windows 10 or Windows 11 PC
• Access to the power button on your device (for hard resets)
• Saved work – close files or ensure auto-save is on before restarting

Step-by-Step

1. Save your work. Press Ctrl+S in any open document or app to save changes. Close programs that have unsaved work if possible.
2. Open the Start menu. Click the Windows icon in the bottom-left corner of the screen, or press the Windows key on your keyboard.
3. Click the Power icon. It looks like a circle with a vertical line at the top. It is usually located at the bottom-left of the Start menu (Windows 10) or bottom-right (Windows 11).
4. Select Restart. Click Restart from the small menu that appears. Windows will begin closing apps and restarting the system automatically.
5. Wait for the reboot. The screen may go black for a minute or two. Do not press the power button during this time unless the system is stuck for more than 10 minutes.

Alternative method using Ctrl+Alt+Delete:

1. Press Ctrl+Alt+Delete simultaneously on your keyboard.
2. Click the Power icon in the bottom-right corner of the screen.
3. Select Restart from the menu.

Alternative method using the command line:

1. Press Windows key + R to open the Run dialog.
2. Type shutdown /r /t 0 (that’s a zero, not the letter O).
3. Press Enter. Windows will restart immediately.

If your PC is frozen (no response to mouse or keyboard):

1. Press and hold the physical power button on your computer case or laptop for 5–10 seconds until the machine turns off completely.
2. Wait 10 seconds.
3. Press the power button again to turn it back on.

Common Mistakes

• Choosing “Shut down” instead of “Restart.” On Windows 10 and 11 with Fast Startup enabled, a shutdown does not fully clear the kernel memory. A restart is the better choice for fixing problems.
• Forcing a hard reset too early. If you press and hold the power button while Windows is still shutting down, you risk corrupting system files. Only use the hard reset when the screen has been frozen for several minutes.
• Restarting during a Windows update. If you see “Getting Windows ready” or a spinning circle, let it finish. Interrupting can cause update failures or boot loops.
• Not saving work. Even with auto-save, some apps lose data on restart. Always save manually before proceeding.

Tips

• Use Restart (not Shut down) when you’re troubleshooting a slow or glitchy PC, because it fully reloads the operating system.
• If you have unsaved work in many apps, use the Restart option from the Start menu rather than the command line, because Windows will prompt you to save if an app blocks shutdown.
• To schedule a restart at a specific time, open Command Prompt and type shutdown /r /t 3600 (restarts in 3600 seconds = 1 hour).
• If you’re restarting to install updates, plug in your laptop to AC power to avoid a mid-update battery failure.

Troubleshooting

Restart option is missing or greyed out. This can happen if a Windows update is in progress or if an administrator has disabled it. Try pressing Ctrl+Alt+Delete and using the power icon there. If that fails, open Command Prompt as administrator and run shutdown /r /t 0.

PC restarts but then hangs on a black screen or spinning dots. Wait at least 10 minutes. If nothing changes, force a hard reset by holding the power button. When it boots, try Start > Power > Restart again. If the problem repeats, boot into Safe Mode (hold Shift while clicking Restart) and run a system file check via Command Prompt: sfc /scannow.

Restart takes more than 15 minutes. This usually indicates a driver or update issue. Let it run for up to 30 minutes. If it’s still stuck, hard reset and then check for pending updates in Settings > Windows Update.

After restart, your apps don’t reopen. Windows doesn’t automatically restore all apps. Check the taskbar or Start menu to relaunch them. Some apps have a “reopen windows on login” setting you can enable.

You accidentally restarted while a big file was transferring. If the file was being copied to an external drive, it may be incomplete. Re-copy the file after the system is back up. If it was a system file, Windows will usually repair it on the next boot.

Frequently Asked Questions

Q: How long should a Windows restart take?
A: Typically 1–3 minutes on a healthy PC. If it takes longer than 10 minutes, something is wrong – wait a bit more, then consider a hard reset.

Q: Is restarting the same as rebooting?
A: Yes, they are the same thing. Both mean turning the system off and back on.

Q: Does restarting delete my files?
A: No. Restarting does not delete personal files, documents, or installed programs. It only closes running processes and reloads the operating system.

Q: Why does my PC restart automatically after an update?
A: Windows is configured to install updates and then restart to complete the process. You can change active hours in Settings > Windows Update to prevent automatic restarts during your work time.

Q: Can I restart Windows from the login screen?
A: Yes. On the login screen, click the power icon in the bottom-right corner and select Restart.

Q: What’s the difference between restart and shutdown on Windows 10/11?
A: Shutdown with Fast Startup enabled saves a kernel image to disk for faster boot, but it doesn’t fully reset the system. Restart fully reloads the kernel, which is why it’s recommended for troubleshooting.
