Hello,
I have a i9-8950HK processor which has been undervolted and held at stock speed with intel XTU up until now. Sadly, due to a BIOS update, intel XTU has reset everything and wont let me change them back. now i am running at 4.2GHZ on all Cores with around 90 degrees idle. I really need to be able to undervolt it again or else i wont be able to properly use my laptop. Anybody got any solutions?
Thanks in Advance,
Sincerely.

Ok, have been provided more information on this. To mitigate undervolt issues, Intel has disabled undervolt completely. I know this is not the news you wanted to hear.
You can read up on undervolt issues here:

There are several ways eliminating undervolt can be performed, BIOS updates being the primary.
Sorry, I wish I had better news.

Ok, which motherboard/system do you have?
You said "due to a bios update". What bios update? What was the bios before the update, and what is it now?
Download, run, and save the results of this utility as a text file:

The Dell update utility is responsible for updating your Dell Bios. I would contact Dell about rolling back to your previous bios version. Then, do not let their update tool update the bios once you have the old version restored.

I did do that myself. I went back to the 1.12.2 version but it still wouldn't work. Then i reinstalled my windows again to see if that would work, nothing. And as for Dell Support, i cant get any support for My region... And when i use a VPN to get into the US support, they just see where the Product was Purchased and tell me to go to MY region's support, which isn't even available...

The windows 10 reinstall - was that a clean install, or a in-place install?

it was an in-place install. But i can try to wipe windows and install it with a USB drive if you recommend that.

That would certainly remove any question of XTU rements being left behind.
