Windows 11 update keeps failing or retrying? Learn how to fix repeated Windows 11 update failures with proven step-by-step solutions.
Why Does Windows 11 Update Keep Failing?
If your Windows 11 update:
- Fails repeatedly
- Installs then rolls back
- Shows “Update failed – Undoing changes”
- Keeps retrying after restart
The problem is usually deeper than a simple glitch.
Common causes include:
- Corrupted update cache
- Broken Windows Update services
- Insufficient disk space
- Damaged system files
- Driver conflicts
- Network instability
Sometimes you may also see related error codes such as:
- 0x80070002 (missing files)
- 0x80070005 (permission denied)
- 0x800f0922 (installation failure)
- 0x80072ee2 (timeout error)
If you’re seeing a specific code, check the detailed error guides for targeted fixes.
Quick Fix Checklist
Before advanced steps:
✔ Restart PC
✔ Restart router
✔ Disable VPN
✔ Disable third-party antivirus
✔ Ensure 20–30 GB free space
Then try updating again.
If it fails again, continue below.
Fix 1: Clear Windows Update Cache
This fixes most repeated failures.
Open Command Prompt (Admin):
net stop wuauserv
net stop bits
net stop cryptsvc
net stop msiserver
Go to:
C:\Windows\SoftwareDistribution
Delete all files inside.
Restart services:
net start wuauserv
net start bits
net start cryptsvc
net start msiserver
Restart PC and try again.
Fix 2: Run SFC and DISM
Corrupted system files often cause updates to fail repeatedly.
Open Command Prompt (Admin):
sfc /scannow
After it completes:
DISM /Online /Cleanup-Image /RestoreHealth
Restart PC.
This also resolves many cases similar to Windows 11 update not installing.
Fix 3: Run Windows Update Troubleshooter
Go to:
Settings → System → Troubleshoot → Other troubleshooters → Windows Update
Apply recommended fixes.
Fix 4: Check Disk Space
Feature updates require:
- 20–30 GB free space
If your system drive is nearly full, updates will fail repeatedly.

Fix 5: Reset Network Configuration
If download phase fails repeatedly:
Open Command Prompt (Admin):
netsh winsock reset
ipconfig /flushdns
Restart PC.
This is especially helpful if you’re facing timeout-related issues like 0x80072ee2.
Fix 6: Perform a Clean Boot
Conflicting startup apps may break update installation.
- Press Windows + R
- Type:
msconfig
- Disable non-Microsoft services
- Restart
Try update again.
Fix 7: Update Device Drivers
Outdated drivers can cause update rollback.
Open Device Manager:
- Check for warning symbols
- Update graphics, chipset, and network drivers
Restart and retry.
Fix 8: Manually Install the Update
- Press Windows + R
- Type:
winver
- Note your Windows version
- Download update manually from Microsoft Update Catalog
- Install manually
Fix 9: Use Windows 11 Installation Assistant
If update keeps failing after multiple attempts:
- Download Windows 11 Installation Assistant
- Choose “Upgrade this PC now”
- Keep personal files and apps
This performs a repair upgrade without deleting data.
Fix 10: Reset This PC (Last Resort)
If multiple updates fail repeatedly:
Settings → System → Recovery → Reset this PC
Choose:
✔ Keep my files
Only use this if all other fixes fail.
Why Does Windows Roll Back Updates?
When Windows detects:
- Driver conflict
- System corruption
- Installation failure
It automatically rolls back to prevent system damage.
That’s why you see:
“Undoing changes made to your computer.”
