Does anyone know the registry key or a new value I can add in the registry to grey (gray) out the power options in Windows so users cannot change the established power scheme?Meaning - I do not want users to be able to change the scheme, make a new one, change their monitor off or HDD off or standby times. Some floor model computers at stores have this setup so customers can't change it, but the store wants the computer on 24x7 so I know it's possible.I should also say I'm not using AD or any GPO's. I'm actually looking to edit the registry manually - or more specifically - modify or add keys that will still let the user look at what the current power scheme is - but it will be gray (grey) out so they cannot change it. Once I find the keys, I'll do this programmatically from a propitiatory tool I've created.

Hi Steve02aa, thanks for the post. I suggest you check the following document regarding power management setting in Windows Vista: Processor Power Management in Windows Vista and Windows Server 2008 http://www.microsoft.com/whdc/system/pnppwr/powermgmt/ProcPowerMgmt.mspx Sean Zhu - MSFT
