Step 1: Restart Your Computer
Before making changes, perform a full restart.
A reboot can clear temporary issues and allow pending updates to complete.
After restarting:
- Open Settings
- Select Windows Update
- Click Check for Updates
If the update still fails, continue with the following steps.
Step 2: Verify Date and Time Settings
Incorrect date and time settings can cause Windows Update failures.
Check Settings
- Open: Settings -> Time & Language -> Date & Time
- Ensure:
✅ Set time automatically
✅ Set time zone automatically
Step 3: Run the Windows Update Troubleshooter
Windows includes a built-in troubleshooting utility.
Launch the Tool
- Open: Settings -> System -> Troubleshoot -> Other troubleshooters
- Locate Windows Update
- Click Run
Allow Windows to investigate and apply any recommended fixes.
Step 4: Clear the Windows Update Cache
Corrupted update files are a common cause of Error 0x80070002.
Stop Update Services
Open Command Prompt as Administrator and run:
net stop wuauserv
net stop bits
Rename the Update Cache
Navigate to: C:\Windows\SoftwareDistribution
Rename the folder to SoftwareDistribution.old
Restart the Services
Run:
net start wuauserv
net start bits
Retry Windows Update
Open: Settings -> Windows Update
and check for updates again.
Windows will create a fresh update cache automatically.
Step 5: Check System Files
Corrupted system files can interfere with updates.
Run System File Checker
Open Command Prompt as Administrator.
Execute: sfc /scannow
This scan may take several minutes.
If corruption is detected, Windows will attempt repairs automatically.
Step 6: Run DISM Repair
If SFC reports issues or updates continue to fail:
Open Command Prompt as Administrator and run: DISM /Online /Cleanup-Image /RestoreHealth
This command repairs the Windows component store used by Windows Update.
Once complete run: sfc /scannow
Step 7: Check Available Disk Space
Windows updates require adequate free space.
Check: Settings → System → Storage
As a general rule:
✅ Remove temporary files
✅ Empty Recycle Bin
✅ Uninstall unused applications
before attempting large updates.
Quick Troubleshooting Checklist
