Hi,

I suggest you to try the below methods and check if it helps.

Method 1: Run the Update Troubleshooter on the computer.

Windows 10 has a built-in troubleshooter to check and fix issues with Update. I would suggest you to run this troubleshooter to check if the issue is with your Windows update.

Refer these steps:

  1. Press Windows key + X, select Control panel.
  2. Change the view by option on the top right to Large icons.
  3. Click on Troubleshooting and click on the view all option on the left panel.
  4. Run the Windows Update troubleshooter.
  5. Restart the system and check if the issue is resolved.  

 

If Method 1 doesn’t help, try Method 2.

Method 2: Reset the Windows Update Components

Refer the link below for the steps to manually reset the Update components and check if it helps.
