A. You can allow your Windows 7 or Windows Server 2008 R2 system to use core parking when it isn't busy irrespective of your power scheme setting by using the command
powercfg -setacvalueindex scheme_current sub_processor bc5038f7-23e0-4960-96da-33abaf5935ec
powercfg -setacvalueindex scheme_current sub_processor bc5038f7-23e0-4960-96da-33abaf5935ec 25
on a four-core system, one of your cores will never be parked and the rest will be parked when your system isn't busy.
You can query the values set by the above command by using the command
powercfg -qh scheme_current sub_processor
This command will return the percentage of your cores that will never park, in addition to other power related settings.
