Q:

How to recover accidentally deleted self signed RDP certificate?

Environment: Windows 2012 on Workgroup setting.
Our Remote Desktop Service was using a self-signed certificate, which was deleted. 
Actions taken to delete are:

MMC > File > Add/Remove Snap in > Certificates > Computer Account > Local Computer > Finish.
Under Console Root hierarchy:
Console Root > Certificates (Local Computer) > Remote Desktop
Certificate selected and deleted.

Is there a way to recover or find that certificate?

A:

The certificate and related private key are gone. You could get the certificate from a client but not the private key. Unless you have a backup you should consider it as lost.
