Enable Remote Desktop remotely with PowerShell (Enable-RemoteDesktop)

Forgot to enable remote desktop? This is bad. The only solution is to go back to the remote computer and then enable RD. Not really. In this blog post I will show you how you can enable RD with PowerShell. Let’s jump in.

The Objective

We want to allow Remote-Desktop connections.

My function has been uploaded to the PowerShell Gallery in order to simply install with the command below.

Install-Module Enable-RemoteDesktop

The Code

Here is the code.

function Enable-RemoteDesktop {
