Windows 10: Win10 capping internet at 20%

Having an odd problem.
Win10 latest insider build appears to be capping my internet at 20%.

If i run ookla speedtest through chrome or ms edge i get close to my full 1 gig connection up and down.

However if I run the ookla app from windows I barely hit 200meg.

I have tried multiple network resets and every possible suggested tweak google has offered with no change.

I have 2 other pcs and they both give similar speeds in bot the browser and the app.

Is there any way to do a scorched earth reset ?
Wipe out everything and start with factory settings for services, registry, network card settings ?

:)

67k CPU capped at 20%

I'm about to reinstall Windows which is not something I'd rather to so I'm coming here to see if people on the OS side of things might have a few ideas on what might be wrong.

I'm currently looking through the event log to see if there is something wrong, it's very apparent that there is since there are almost 75k events logged, almost all of which appear to have started on the 6th of this month.

 

Cat killed my CAP LOCK Beep sound :-(

I've done the steps listed here before joining this forum. None of these work.
but I do have it setup now to flash the window if I press the caps.
I may just try the restore option and roll back drivers,,,

 

What will happen on Jan 20, 2016?


Strollin: I understand your suggestion, but that means I'll have to re-install all my sofftware etc. again. This is not an enticing thought at all.

LCDR: I tried the old activation code I used before - it is the same on you posted.

I tried the steps listed at the WinAero site. Last one failed because it said the server could not be located. But I did get the Jan 20, 2016 date back. So that's something.
