After writing my post about “Server Manager & WinRM” I decided to write a script to take care of adding and modifying the TrustedHosts list.

Here are two scripts, first one is menu-based script which would run entirely in the PowerShell/ISE window and second one is GUI; Graphical interface has been created using “SAPIEN PrimalForm (Community Edition)” and then the working part added to it.
