I just saw a tweak to enable more CPU's/Thread's to be used during OS booting and it can be found in MSConfig Advanced Boot options. The problem is that I get an error when I try to save changes made: "System configuration cannot save the original boot configuration for later restoration. Boot changes will be reverted". I try to make changes in Safe Mode, but it didn't work. I also tried NSudo System and Trusted Installer permissions for MSConfig, but it also didn't work... If there's another way to force maximum CPU cores/threads for OS booting, then I am all ears .
