How to Make my Powershell script discover a Desktop on my network and delete user profiles remotely - powershell

Question

I am fairly new with powershell scripting and trying to learn. I am trying to create a PS1 file that runs with a GUI for easy use for other people on my team, that can delete profiles off of a Desktop/Laptop remotely. I have a script below that works for local profiles and would like to enhance it for remote PC's so we dont physically have to collect devices when cleaning up desktops/laptops that are filled with profiles. These computers have a program that runs that refreshes the profiles daily so a script that cleans based on days since last log in will not work.
