Cannot change priority of APB in task manager.

[Micrieveritiem]

So I've tried to change my APB priority to high in task manager, but I get an error that says "unable to change priority, access is denied" I've tried most of the methods I found on the internet to fix it, none of them helped, but I've also read that EAC is causing that, if it is, is there any workarounds to change my APB priority to high?

same problem, and otherwise my net is being eaten by browser so i have to min everything else manually

hope this gets a fix
