Add Device Idle Policy to Power Options in Windows 10

How to Add the Device idle policy option to Power Options in Windows 10

In Windows 10 you can add the "Device idle policy" option to the Power Options applet of the classic Control Panel. It determines whether conservation idle timeouts or performance idle timeouts are used for devices that are integrated with Windows kernel power manager device idle detection. It is a hidden option that is not visible by default.

The option Device idle policy is available in Windows Vista with Service Pack 1 (SP1), Windows Server 2008 R2, and later versions of Windows.

You can add or remove it from Power Options using either a Registry tweak or powercfg. In this article, we will remove both methods.
