(0x80070643) Error when getting Windows update. Troubleshooter goes on and on.

Question

Went to update software and I got this error.

(0x80070643)

Ran the troubleshooter. It took a long time and didn't fix the problem.

Also, stop blaming 3rd party software. The Windows Defender lets things through, and also when it does, it might flag it, but can't remove it. SO EVERYONE GETS ANOTHER ANTI-VIRUS if they seriously want to protect their computer.

So what is the fix without a lot of stupid complicated steps. Please no links to another post. I am not downloading software.

Hello,

According to your description, the error seems met by few people. So first I consider that it may be related to the size of the Recovery Environment's partition. The Windows Recovery Environment (WinRE) is used to repair or recover from issues affecting Windows. You could find the information and steps in the link below. Try to manually resize your partition.

If the issue still insists, try to reset Windows Update Component and repair .net framework component.

1.Type “Control Panel” into the search bar and open it.

Go to “Programs” > “Programs and Features”.

Find Microsoft .NET Framework from the list, click on it, and select “Uninstall/Change”.

In the new window that appears, select “Repair .NET Framework to its original state” and click “Next”.

Once the repair process is complete, restart your computer and try updating again.

2.Try to reset Windows Update components manually by following the steps below:
