Practical reference for using powercfg.exe to list, modify, and enforce Windows power schemes, CPU performance policies, and advanced power settings

Lists all power schemes

PS C:\Users\wuseman> powercfg.exe /LIST

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced) *
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance)

powercfg -setactive SCHEME_CURRENT

Disable CPU core parking

powercfg -setacvalueindex SCHEME_CURRENT SUB_PROCESSOR CPMINCORES 100
powercfg -setactive SCHEME_CURRENT
