Thank you, I ended up with a successful clean install

Helpful, but it doesn't appear fixed.

I went through all 3 methods and none worked. However, during method 1 when troubleshooting was finished, it fixed 3 of the 5 (Please see attachment).

Answer 5

Hi John,

As per the description, I understand that you are getting an error code.

Let’s try the methods and check if that fixes the issue.

Method 1:

I would suggest you to refer to the link given below and check.

Windows Update Troubleshooter

Method 2:

I would suggest you to reset Windows updates componentsand check if that helps.

Method 3:

 I suggest you to perform clean boot and check, using this Microsoft Article because may be a third party application is causing this issue.

**NOTE:**A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists. If the computer is connected to a network, network policy settings may prevent you from following these steps.

Once you perform clean boot do refer to the section **“How to reset the computer to start normally after clean boot troubleshooting”**to boot the computer in normal mode.
