Hi Bobby,

Thank you for posting your query in Microsoft Community.

Sorry for the inconvenience caused.

Please follow the methods below and see if it helps:


Method 1:

I suggest you to run Windows Update Troubleshooter

Follow the below steps:

1.     Type troubleshooting in the search bar. 

2.     Select Troubleshooting.

3.     Select View all on the top left corner.

4.     Click on windows update.

5.     Follow the on-screen instructions to run the troubleshooter


Method 2:

If the issue still persists, try the below method and check if it helps or not:

I would recommend you to reset the windows update component manually. Resetting Windows Update Components will fix corrupt Windows Update Components and help you to install the Updates quickly. Follow the below steps:

1. Press Windows Key + X on the keyboard and then select “Command Prompt (Admin)” from the menu.

2. Stop the BITS, CryptographicMSI Installer and the Windows Update Services. To do this, type the following commands at a command prompt. Press the “ENTER” key after you type each command.

                           net stop wuauserv

                           net stop cryptSvc

                           net stop bits

                           net stop msiserver

3. Now rename the SoftwareDistribution and Catroot2 folder. You can do this by typing the following commands in the Command Prompt. Press the “ENTER” key after you type each command.

                          ren <C:\Windows\SoftwareDistribution SoftwareDistribution.old>

                          ren <C:\Windows\System32\catroot2 Catroot2.old>

4. Now, let’s restart the BITS, Cryptographic, MSI Installer and the Windows Update Services. Type the following commands in the Command Prompt for this. Press the ENTER key after you type each command.

                        net start wuauserv

                        net start cryptSvc

                        net start bits 

                        net start msiserver

5. Type Exit in the Command Prompt to close it and then restart the computer.
