How to Fix Windows Error 0x80070005

What Causes This?

Windows error 0x80070005 usually means Access Denied. It happens when Windows Update, Microsoft Store, System Restore, or another system task does not have permission to read, write, or change a file, folder, registry key, or service it needs. In many cases, the problem is caused by broken update components, security software blocking access, damaged system files, or a user account that does not have the right administrative permissions.

Common Symptoms

• Windows Update fails with error 0x80070005
• Microsoft Store apps will not install or update
• System Restore fails partway through
• You see Access Denied messages during setup or updates
• Some Windows services will not start correctly

How to Fix It Manually

1. Restart your PC and sign in with an administrator account

   • Save your work and restart Windows.
   • Make sure you are using an account with administrator rights.
   • To check, press Windows + I to open Settings, then go to Accounts > Your info and confirm it says Administrator.

2. Run the Windows Update troubleshooter

   • Press Windows + I to open Settings.
   • Go to System > Troubleshoot > Other troubleshooters.
   • Find Windows Update and click Run.
   • Let Windows apply any fixes, then restart your PC and try the update again.

3. Reset Windows Update components

   • Press Start, type cmd.
   • Right-click Command Prompt and choose Run as administrator.
   • Run these commands one at a time:

     net stop wuauserv
     net stop bits
     net stop cryptsvc
     net stop msiserver
     ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
     ren C:\Windows\System32\catroot2 catroot2.old
     net start wuauserv
     net start bits
     net start cryptsvc
     net start msiserver

   • Restart your PC after the commands finish.

4. Repair damaged system files

   • Open Command Prompt as administrator again.
   • Run:

     sfc /scannow

   • Wait for the scan to complete.
   • Then run:

     DISM /Online /Cleanup-Image /RestoreHealth

   • Restart your PC when both scans are done.

5. Temporarily disable third-party antivirus

   • If you use antivirus other than Microsoft Defender, open it and temporarily disable real-time protection.
   • Try the update or task again.
   • If it works, re-enable protection and check the antivirus settings for anything blocking Windows Update, Store, or system changes.

6. Check the affected service permissions

   • Press Windows + R, type services.msc, and press Enter.
   • Find Windows Update and Background Intelligent Transfer Service.
   • Double-click each one and make sure Startup type is not set to Disabled.
   • Click Start if the service is stopped.

7. Free up space and remove update clutter

   • Press Windows + I, then go to System > Storage.
   • Remove temporary files you do not need.
   • Low disk space or corrupted temporary update files can sometimes trigger access-related update failures.
