The RDP Ghost is real.
Recently, when connecting to a reasonably-sleepy Windows system, I’ve seen the RDP Ghost.
An 8 bit rendition of a scary, scary ghost. It scared me.
If you’ve seen it, you’re not alone. It’s a thing.
I hope - one day - to capture a screenshot of this apparition.
The Rules appear to be that you can never be ready for a screenshot when RDP Ghost appears.
Update 22/04/17: I WAS READY! Kinda. And caught enough that I can understand the cause and the effect.
The good news is, you’re probably not hacked by a supernatural force. Probably. It’s just Windows trying to draw the sign-in guy before it’s ready!
