KB4025339 Fails Install 0x80070564

Thanks
I am trying Eagle 51's suggestions now. Windows Update troubleshooter found a bunch of errors and fixed all but one.The update is trying to download KB4025339 again. I'll see what happens. At step one troubleshooter finishes with one error unresolved "Potential Windows Update Database Error Detected-Not Fixed". Windows update stalled at 0%.

At step 2 same troubleshooter error. The KB finished a new download failed to install.
Did step 3 KB has downloaded but fails to install.

If Eagle's suggestion doesn't work I'll try EdTittel's suggestion

Tried bothe Eagle & Ed 's suggestions - do not work. Anyone else?

I have noticed that the latest update for my nvidia drivers has failed to update. Wondering about that!

 

Running Optimize literally does nothing; in PS it yields an error

After doing a clean install of Windows 10 20H2 (OS Build 19042.906) and fully updating it, and updating all of the Dell drivers from Dell.com, I tried the following Optimize and Defrag options from How to Optimize and Defragment Drives in Windows 10 (tenforums.com/tutorials/8933-optimize-defrag-drives-windows-10-a.html):

• OPTION ONE: To Optimize Drives in Optimize Drives Tool: Steps 2, 3, and 4,
• OPTION TWO: To Optimize Drives in Command Prompt: Step 2, and
• OPTION THREE: To Optimize Drives in PowerShell: Step 3

The four steps attempted from Options 1 and 2 resulted in no notice action; i.e., it appeared as though nothing happened after executing the commands.

When I ran Step 3 of Option 3, I received the following error message.

What does this mean and now what do I do?

Thanks!
