win7 unpark cpus
after upgrading to pro this feature reset my registry to park cpus. in windows7 the attribute is masked from the gui by default it seems so unhide it then you can modify it in the gui. the relevant guid doesnt work in powercfg directly for some reason though.
powercfg -attributes 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE
in windows server 2016 you can hit it directly of course:
Powercfg -setacvalueindex scheme_current sub_processor CPMINCORES 100
Powercfg -setacvalueindex scheme_current sub_processor CPMINCORES 100
Powercfg -setactive scheme_current
