Windows update error 800F081F

[Steve202]

I can't seem to solve this. Picked a PC up the other day and the customer said he can't install any updates. Had a quick look and brought back to the workshop.

Hard drive tested fine so decided to use tweaking.com AIO and run the update service repair from that. That didn't work and so tried to manually reset the update service myself, nothing.

SFC doesn't pick anything up and so tried the windows system readiness tool as I've had some success with that in the past.

Weirdly, if I try and run something as administrator, nothing happens and the cursor will just sit there spinning away.

It's Windows 7 HP 64bit.

Any ideas?

Have you ruled out malware?

+1

A scan with Malwarebytes last night revealed nothing.

Bad AHCI drivers? Try removing whatever is installed and use the default Windows drivers and see if that fixes it.

 

[cypress]

Root Kit scanners as well?

 

[Mike McCall]

Have you run this Microsoft tool?

Edit: Answered my own question by re-reading your post. That said, MS recommends repairing the installation if their tool doesn't fix the problem. Have you tried repairing the installation?

 

[Steve202]

Nothing on the rootkit scanners. Every virus,malware, rootkit scan comes back clean

Not yet, but I've got a feeling this is going to be the only option. The PC has started to blue screen on me now, system_service_exception.

chkdsk /r?

Check to see if Cryptographic Services are running.

I think at this point I'd try to repair the installation.

 

[Steve202]

I've ran the hardware diagnostics again and some errors appeared on memtest that didn't show the other day. The only difference is when I test the memory, I normally run it for 4 hours however these errors appeared after 7 hours. This might explain the blue screen but the issues with Windows Update?

So did you try my suggestion?

Yeah, no luck.

 

[Mike McCall]

And repairing the installation hasn't worked either?

I haven't done that as the memory test has been running most of the day.

If there are memory errors, why would anyone bother to do any other type of repair attempt before replacing the failed ram?

Because the memory errors didn't show up on the initial diagnostics

If you have memory errors....ALL KINDS OF STRANGE THINGS CAN HAPPEN!

I suggest you fix this issue before proceeding.

Swap out the ram and go on to the next test. If problems continue then its more than just ram.
No point running ram tests for hours.
