I only tested it on a Windows 10 machine however (I had no Windows 7 machine to test it on) so there is a possibility that it could even be working for the start menu button on a windows 7 (could someone confirm this?). It may also be a solution for the shutdown in the start menu but I couldn't set it on "Change User". The first one presents a solution for the hardware power button. I have 2 solutions I would like to share with you. Undoing configuration changes is not always that easy.

The current scheme may be a default scheme and changing without backup is sometimes risky.

Before I explain you my solutions, I would advise you to copy the current power scheme and work with that copy instead of changing the current scheme.
