Windows Troubleshooting / Startup & Boot
How to Fix Windows 11 When It Is Stuck on Restarting
Quick answer
If you just installed updates, wait. Restart is when Windows often finishes servicing; twenty minutes on a spinning circle can still be normal on a slow disk. If there is no disk activity for a long time, hold the power button until it is off, wait a minute, then power on. If you then see Automatic Repair, switch to that guide. If you asked for Shut down and the machine never goes dark, use [won't shut down](/guides/windows-11-wont-shut-down).
Quick diagnosis
If several of these match what you see, you are in the right guide.
- The screen says Restarting and never changes
- A spinning circle after you chose Restart
- Restart from Windows Update never finishes
- The PC reboots into the same Restarting screen
Possible causes
- Windows Update applying packages during the restart
- A driver that never unloads
- A full or failing system drive
- Fast Startup leftovers colliding with a Restart (less common than with Shut down)
- A pending restart that was interrupted earlier
What you need
- Patience on the first hang
- Windows Recovery if the next boot fails
What this problem usually means
Restart unloads Windows and loads it again. Shut down (especially with Fast Startup) can stop short of a full firmware reboot. Hanging on Restarting means the unload or the next boot did not finish. Forcing power off mid-update has risk; waiting too long on a truly frozen machine also has cost. Disk light or fan changes are better signals than the circle alone.
Before you start
- Leave it for a reasonable stretch if Update said it needed a restart.
- Do not yank a desktop PSU switch during "Working on updates" unless it has been hours and the machine is silent.
- A laptop should stay plugged in.
Quick fixes
1. Wait, then a clean power cycle
After a long silent hang: hold power until the machine is off. Unplug the laptop brick for a minute if you can. Power on and let Windows finish whatever it was applying. One clean cycle is better than five short ones.
Step-by-step troubleshooting
If you get back to the desktop
Open Windows Update and let it complete. Low disk space makes restart hangs more likely, free space. If Update reports a failed install, use Windows Update install failed, not more Restart clicks.
If you land in recovery
Advanced options → Uninstall Updates if the hang started after patching. Startup Repair once. See Automatic Repair loop if recovery repeats. Safe Mode is for a desktop that starts but Restart hangs later, not for a PC that never leaves the circle.
Pending restart that never clears
Some apps (office suites, VPN, endpoint tools) keep a "restart required" toast forever. Restart from Start after closing those apps. If Restart from Settings → Windows Update is the only action that hangs, the update payload is the suspect, not the Start menu.
Where did Restart stop?
Choose an answer. The next question appears below, no account or download required.
Wait. This is servicing. Only force power if it is frozen for a very long time with no progress and no disk activity.
Wait a while on a hard disk. Then one clean power-off. If the next boot is repair screens, follow Automatic Repair, not more Restart from a USB "optimizer."
You have a usable session. Finish Update, check disk space, try Safe Mode Restart as a test.
How to know the problem is fixed
Start → Restart reaches the sign-in screen without a long silent hang, twice. Update does not immediately demand another restart that hangs again.
If the problem continues
Check drive health if copies fail or SMART already warned you. A restart hang plus a dying SSD is a backup problem first. Repair-install from Microsoft media is the next software step after backups, not a third-party boot disc.
When this may be hardware failure
Restart hangs that survive Safe Mode and a clean Windows repair, plus failing SMART or random power loss, make the drive or PSU more likely. A stuck Restarting screen alone does not prove a part is dead.
Common mistakes to avoid
- Tapping the power button every thirty seconds.
- Downloading a restart-repair utility from an ad.
- Treating a shutdown hang as the same article as a restart hang.
Frequently asked questions
How long should I wait on "Restarting"?
There is no official minute count. Feature updates can sit for a long time. If the fan is working and the disk light blinks, keep waiting. A totally silent machine for a very long stretch is the usual point to power-cycle once.
Is this Fast Startup?
Fast Startup mainly changes Shut down. Restart is supposed to skip that hybrid path. Still try Fast Startup off if Shut down and Restart both misbehave, see the shutdown guide.
