Fix Windows Error 0x80070005 - Access Denied

Seeing error 0x80070005 usually means Windows is blocking an installer or update from touching your own system files. It is incredibly frustrating when you have administrative rights but Windows refuses to let you perform basic tasks.

Why this happens

This is typically caused by corrupted cache files, conflicting account credentials, or restricted file system permissions. It essentially stops the installer from writing the necessary data to your drive.

What you'll need

You will need an active internet connection and Administrator-level access to your Windows user account to run the diagnostic tools and command prompts.

Steps

1. 01
   Reset the Store cache by pressing Win + R, typing wsreset.exe, and hitting Enter; a window will open and close automatically.
2. 02
   Remove duplicate Microsoft accounts by going to Settings / Accounts / Your accounts and deleting any redundant entries of your email address.
3. 03
   Run the built-in troubleshooter by navigating to Settings / System / Troubleshoot / Other troubleshooters and selecting Run next to Windows Update.
4. 04
   Open Command Prompt as an administrator, type sfc /scannow, and let the process complete to repair system files.
5. 05
   If an installer fails, right-click the file and select Run as administrator to grant it the necessary permissions to write to your system folders.
