Windows 10: Force One Program To Run Behind Another

I currently have Cortana set up to operate Kodi which works great, but after each command i have to tell it to close the window, it displays an error message and often displays in fullscreen, all of which is very clunky.

I'm looking for a way to force Cortana to always run behind Kodi, so that all this stuff is hidden, the opposite to always on top, but can't find a solution. How can i achieve this?

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Is there a way to force a program to use a secondary GPU?

I have 2 GPU's (Nvidia GTX 970 and 1080) and I want to force a program to use the 1080 for certain programs/games. Going to Settings>System>Display>Graphics Settings should give me the option to switch GPU's. Unfortunately it does not list both of my GPU's
nor does it allow me to change to another one, only the default GPU is chosen (the 970). This is a desktop computer and I have tried the Nvidia control panel and UEFI settings without much luck. If I tried selecting a program to run on my 1080 (through the
Nvidia control panel), it would still run it on the 970. I have tried switching the GPU's around with not much luck there either. If I can suggest to Microsoft the option in the Graphics Settings to list both GPU's for selection, that would be great. Otherwise
I don't know what to do. Does anyone have any suggestions? Thank you for your time.

 

Running Programs for a standard user

Hello

You mentioned checking the the box 'Run as Administrator'

This is the opposite of what I require ,I wanted to avoid running programs as admin . By unchecking 'Run As Administrator' I am still getting an admin credential verification prompt

Any further suggestions ?
