How to permanently change Windows 10 display setting using Registry or Commands?

Question

Is there a way to permanently change Windows 10 display setting using C# code. Changes that I have to do are as follows:

1. sleep: Never 2. screenSaver: disable 3. HardDisk(Sleep) : Never

I have a media player setup, and once this player is installed, the setting should be reflected. Don't want temporary changes like while the program is running, it will prevent sleep mode or something like that.

I am using .Net 4.5 with visual studio 2015

Instead of using registry i found a solution to solve these issue using command prompt and the command are:

require Administrative permission

To disable sleep run using cmd

• powercfg -x -standby-timeout-ac 0

For HardDisk (Sleep->Never)

• powercfg -Change -disk-timeout-ac 0

For monitor

• powercfg -Change -monitor-timeout-ac 0
