Fix Windows Update Error 0x80070005 – Access Denied 2026

Microsoft's built-in troubleshooter automatically detects and fixes common Windows Update issues including permission problems.

1. Press Windows + I to open Settings
2. Navigate to System → Troubleshoot → Other troubleshooters
3. Locate Windows Update and click Run
4. Allow the troubleshooter to scan for issues (this takes 2-5 minutes)
5. Follow any recommended actions presented by the troubleshooter
6. Restart your computer when prompted

Verification: Open Settings → Windows Update and click Check for updates. The error should no longer appear.

This method stops Windows Update services, clears the update cache, and restarts services with proper permissions.

1. Press Windows + X and select Terminal (Admin)
2. Stop Windows Update services by running these commands:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver

3. Rename the SoftwareDistribution and catroot2 folders:

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old

4. Restart the Windows Update services:

net start wuauserv
net start cryptSvc
net start bits
net start msiserver

5. Close Command Prompt and restart your computer

Verification: Check Windows Update again. The system will recreate the folders and download fresh update metadata.

Corrupted system files often cause permission errors. SFC and DISM repair these files using Windows component store.

1. Open Terminal (Admin) from the Windows + X menu
2. Run System File Checker to scan for corrupted files:

sfc /scannow

3. Wait for the scan to complete (15-30 minutes). If SFC finds issues, run DISM to repair the component store:

DISM /Online /Cleanup-Image /RestoreHealth

4. After DISM completes, run SFC again to ensure all files are repaired:

sfc /scannow

5. Restart your computer and test Windows Update

Verification: Run sfc /verifyonly to confirm system integrity, then check Windows Update functionality.

Incorrect registry permissions or Group Policy settings can block Windows Update access. This method resets these configurations.

1. Press Windows + R, type gpedit.msc, and press Enter
2. Navigate to Computer Configuration → Administrative Templates → Windows Components → Windows Update
3. Double-click Configure Automatic Updates and set it to Not Configured
4. Repeat for Specify intranet Microsoft update service location and Remove access to use all Windows Update features
5. Close Group Policy Editor and open Terminal (Admin)
6. Reset Windows Update registry permissions:

takeown /f C:\Windows\SoftwareDistribution /r /d y
icacls C:\Windows\SoftwareDistribution /grant administrators:F /t

7. Force Group Policy update:

gpupdate /force

8. Restart your computer

Verification: Check if the "Some settings are managed by your organization" message disappears from Windows Update settings.

When other methods fail, completely rebuilding the Windows Update database often resolves persistent 0x80070005 errors.

1. Boot into Safe Mode: Hold Shift while clicking Restart, then Troubleshoot → Advanced options → Startup Settings → Restart → Press 4
2. Open Terminal (Admin) in Safe Mode
3. Stop all Windows Update related services:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
net stop dosvc

4. Delete the Windows Update database and cache:

del /f /s /q C:\Windows\SoftwareDistribution\*.*
rmdir /s /q C:\Windows\SoftwareDistribution
rmdir /s /q C:\Windows\System32\catroot2

5. Re-register Windows Update DLL files:

regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 wuaueng1.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
regsvr32 wups2.dll
regsvr32 wuweb.dll

6. Restart services and reboot normally:

net start wuauserv
net start cryptSvc
net start bits
net start msiserver

7. Restart your computer normally

Verification: Windows will rebuild the update database on first check. This process may take 10-15 minutes.
