Windows 11 Update Stuck at 0%? Here's How to Fix It
Key Takeaway: A Windows 11 update sitting at 0% does not automatically mean your PC is broken. Start with the least disruptive fixes: give the update a little time, restart normally if it is clearly stuck, check your connection and storage, run Microsoft's Windows Update troubleshooter, and then repair damaged system files if necessary. This guide takes you through those steps in the safest order.
Why is Windows 11 Update stuck at 0%?
There is no single reason for a Windows 11 update to remain at 0%. The download can be affected by an unstable internet connection, insufficient storage, a problem with Windows Update itself, damaged update files, or another Windows component that is preventing the update process from moving forward.
Microsoft's current troubleshooting guidance specifically tells users with Windows Update stuck at 0% or 100% to restart the PC, check the internet connection and check available disk space. Microsoft also recommends running the Windows Update troubleshooter if the problem continues.
| What you see | Most useful first check | What to try next |
|---|---|---|
| 0% for a short time | Wait and check network activity | Do not interrupt the update immediately |
| 0% for a long time | Restart Windows normally | Run Windows Update troubleshooter |
| 0% with internet problems | Check Wi-Fi or Ethernet | Reconnect and try again |
| 0% with very little storage | Check C: drive space | Use Storage Sense or Cleanup recommendations |
| 0% after repeated attempts | Run the troubleshooter | Repair Windows system files |
| Update repeatedly fails | Look for an error code | Use Microsoft's error-specific troubleshooting |
Before you do anything, check whether it is really stuck
The percentage shown by Windows Update is not a reliable indication of how much time is remaining. A large update can spend time preparing files, checking the system or performing other work without the percentage changing immediately.
If the PC is still responding normally, give it some time before interrupting the process. If Windows is completely unresponsive or the update has remained at exactly 0% through repeated attempts, continue with the troubleshooting steps below.
1. Restart your Windows 11 PC
This is the simplest fix, and Microsoft specifically recommends restarting when Windows Update is stuck at 0% or 100%.
Save your work, close your applications and select:
Start > Power > Restart
After Windows starts again, open:
Settings > Windows Update
Then select Check for updates.
If the update begins moving again, you do not need to perform the more advanced fixes below.
2. Check your internet connection
Windows Update needs an internet connection to download updates. Microsoft recommends checking the connection when an update is stuck at 0%.
On Windows 11, go to:
Start > Settings > Network & internet
Make sure your Wi-Fi or Ethernet connection is active.
Then try a simple test: open a few websites in your browser. If pages are loading slowly, disconnecting or failing to load, fix the connection before troubleshooting Windows Update further.
If possible, a stable Ethernet connection can also help eliminate Wi-Fi instability as the cause.
3. Check how much storage space is available
Low storage can cause problems installing Windows updates. Microsoft says insufficient disk space can lead to trouble installing updates and recommends freeing space when necessary.
To check your storage:
Start > Settings > System > Storage
You can also open File Explorer > This PC and check the available space on the Windows drive, normally C:.
If your drive is nearly full, use Windows' built-in cleanup options rather than randomly deleting system folders.
Use Cleanup recommendations
Go to:
Settings > System > Storage > Cleanup recommendations
Review temporary files, large or unused files and unused applications. Remove only items you are comfortable deleting. Microsoft also provides Storage Sense to automatically remove unnecessary temporary files.
4. Run the Windows Update troubleshooter
This is the next step I would recommend instead of immediately using complicated Command Prompt commands.
Microsoft currently directs Windows 11 users to the automated Windows Update troubleshooter in the Get Help app. The troubleshooter can diagnose common Windows Update problems and attempt to fix them automatically.
Open the Get Help app and search for:
Windows Update troubleshooter
Follow the diagnostic steps it provides.
If you prefer the Windows Settings route, Microsoft also lists:
Start > Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run
Restart the PC after the troubleshooter finishes and check Windows Update again.
5. Check whether Windows Update is repeatedly downloading the same update
If the update reaches 0%, fails, and then starts from 0% again every time you check for updates, the problem may be more than a temporary connection issue.
Go to:
Settings > Windows Update > Update history
Look for recent failed updates and note any error code displayed next to them.
Do not ignore the error code if Windows provides one. A code such as 0x80070003, 0x80246007 or 0x80240034 can point toward a different underlying problem, and Microsoft provides separate troubleshooting guidance for many update errors.
6. Repair Windows system files with DISM and SFC
If Windows Update continues to fail and you suspect damaged Windows components, Microsoft's built-in DISM and System File Checker tools can repair missing or corrupted system files. Microsoft recommends running DISM before SFC.
First, search Windows for:
Command Prompt
Right-click it and choose Run as administrator.
Run this command:
DISM.exe /Online /Cleanup-image /Restorehealth
Wait for DISM to finish. It can take several minutes.
Then run:
sfc /scannow
Do not close the Command Prompt window while SFC is scanning. Microsoft says SFC checks protected system files and replaces corrupted files with a cached copy when possible.
When both operations finish, restart the computer and try Windows Update again.
7. Reset Windows Update components if the problem keeps returning
If Windows Update repeatedly fails even after the basic troubleshooting and system-file repair steps, resetting Windows Update components is a more advanced option.
Microsoft lists resetting Windows Update components among the possible remedies for several Windows update errors, including cases involving missing or damaged update files.
This is not the first thing I would try. Start with the built-in troubleshooter, storage check, connection check and DISM/SFC. If the same update repeatedly fails, use Microsoft's current instructions for resetting Windows Update components rather than copying an old command sequence from an unknown website.
8. Disconnect unnecessary external devices
If the update is still failing, temporarily disconnect devices you do not need during the update, such as external storage drives, USB accessories and other peripherals.
Microsoft's upgrade troubleshooting guidance lists disconnecting external devices as a possible step for certain installation errors.
Keep essential devices such as your keyboard, mouse and network connection connected.
9. Check the error code before trying more aggressive fixes
If Windows Update gives you an error code, search for that exact code rather than repeatedly trying generic fixes.
| Error | What Microsoft says it can indicate | Useful direction |
|---|---|---|
| 0x80240034 | Download was interrupted | Check the connection and restart the update |
| 0x80246007 | Downloaded update files are missing or corrupt | Try temporary update-file cleanup and troubleshooting |
| 0x80070003 | Windows cannot find a required path | Run the troubleshooter and consider resetting update components |
| 0x80070020 | Another process may be using a required file | Restart and check background software |
| 0x80070422 | A required service may be disabled | Check Windows Update services |
These examples come from Microsoft's current Windows upgrade and installation troubleshooting documentation. The exact cause can vary by device, so do not assume an error code guarantees one particular fix.
What if Windows 11 is stuck at 0% after a restart?
If Windows restarts and the update returns to 0%, do not immediately repeat the same restart cycle.
Instead, check these four things:
- Internet: Is the PC connected reliably?
- Storage: Does the Windows drive have enough free space?
- Update history: Is Windows showing an error code?
- System health: Have you run the Windows Update troubleshooter and DISM/SFC?
If all four look normal but the same update continues failing, the problem may require more specific troubleshooting based on the update's error code or the particular Windows version installed.
Should you use a third-party Windows Update fixer?
I would avoid it.
You do not need a random “one-click Windows Update repair” program just because an update is stuck at 0%. Windows already includes Get Help troubleshooters, Storage Sense, DISM and SFC, while Microsoft provides official troubleshooting documentation for Windows Update problems.
Third-party repair utilities can also make it harder to determine what actually fixed or changed your system.
A simple order to fix Windows 11 Update stuck at 0%
| Order | Action | Risk level |
|---|---|---|
| 1 | Wait briefly and confirm the PC is responsive | Very low |
| 2 | Restart Windows normally | Very low |
| 3 | Check internet connection | Very low |
| 4 | Check available storage | Very low |
| 5 | Run Windows Update troubleshooter | Low |
| 6 | Check Update history and error codes | Low |
| 7 | Run DISM and SFC | Low to moderate |
| 8 | Reset Windows Update components | Advanced |
| 9 | Use Microsoft's error-specific recovery options | Advanced |
Pro Tip: Do not jump straight to the most complicated fix. If a Windows Update problem can be solved by fixing the network connection or freeing storage, there is no reason to reset Windows Update components or reinstall Windows.
15-minute Windows 11 Update checklist
- Save your work.
- Check that your internet connection is stable.
- Check available space on the Windows drive.
- Restart the PC normally.
- Open Settings > Windows Update.
- Select Check for updates.

Final thoughts
Windows 11 Update stuck at 0% looks alarming, but it does not automatically mean you need to reinstall Windows or replace your PC. Start with the boring fixes that are easiest to verify: internet, storage and a normal restart. Then use Microsoft's built-in Windows Update troubleshooter.
If the problem survives those steps, look at the actual error code and move to DISM, SFC or Windows Update component repair. The important part is to troubleshoot the cause instead of repeatedly forcing the computer off and hoping the next update attempt works.
