<#
This Program goes through all the remote pcs iteratively and adds files, runs programs, or deletes things
You need to make sure that you are running powershell as an ADMIN or else it will not work
If the password to enter the virtual machines or remote pcs is changed you will need to change it in the two password sections 
Make sure powershell is enabled. The command for that is: Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypas
Create an installer package (.mst or .msi) 
Bypass dual verification regedit -> HKEY_LOCAL_MACHINE -> Software -> Microsoft -> Terminal Server Client -> New -> DWORD
