How to Solve Errors

Try these solutions one at a time, restarting your computer after each attempt:

Run the Windows Update Troubleshooter

  2. Go to Update & Security.
  3. Select Troubleshoot from the left-hand menu.
  4. Click Additional troubleshooters.
  5. Choose Windows Update and click Run the troubleshooter.

Check Your Internet Connection

Ensure your internet connection is stable and functioning correctly. Try:

  • Restarting your modem and router.

  • Testing your connection speed using an online tool.

  • Temporarily disabling your firewall or antivirus software to see if it's interfering.

Reset Windows Update Components

  1. Open Command Prompt as an administrator. (Right-click the Start button and select "Command Prompt (Admin)").
  2. Enter the following commands, pressing Enter after each:
    • 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 services you stopped in step 2, using these commands (replacing "start" with "stop" if they are already running):

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

Perform a System File Check

  1. Open Command Prompt as an administrator.
  2. Type sfc /scannow and press Enter. This will scan for and attempt to repair corrupted system files.

Use the DISM Tool

The Deployment Image Servicing and Management (DISM) tool can help fix corrupted Windows image files. Run these commands in Command Prompt as administrator:

  • DISM /Online /Cleanup-Image /CheckHealth (Checks for corruption)
  • DISM /Online /Cleanup-Image /ScanHealth (Scans the image for more detailed information about corruption)
  • DISM /Online /Cleanup-Image /RestoreHealth (Attempts to repair corrupted files)

Update Network Drivers

Outdated or incompatible network drivers can cause connectivity issues. Visit your computer manufacturer's website or use Device Manager to update your network adapter driver.

Reinstall Windows (Last Resort)

If all else fails, reinstalling Windows may be necessary to resolve deeply rooted system problems. Remember to back up your important data before proceeding. You can download a fresh copy of Windows from the Microsoft website: https://www.microsoft.com/en-us/software-download/windows10
