Check Disk Space

Ensure your hard drive has sufficient free space for updates:

  • Attempt the update or installation again.

Run System File Checker

The System File Checker (SFC) tool scans for and repairs corrupted system files.

  1. Open Command Prompt as administrator (right-click on the Start menu icon, select "Command Prompt (Admin)").
  2. Type sfc /scannow and press Enter.

Reset Windows Update Components

Resetting Windows Update components can resolve underlying issues.

  1. Open Command Prompt as administrator.
  2. Run the following commands one by one, pressing Enter after each:
    • net stop wuauserv
