Revert to free license from corporate trial

So I was blocked out of my home PC because there had been a powercut so I was trying to be smart with some of the corporate features to try and get back in. It never worked out, but I had used the corporate trial to do this.

Problem is now I'm stuck on this and now the corporate trial has ended I want to get back to my free / personal account that I had before. Is there anyway to do this, remove the corporate trial that's expired and just be back to my single desktop free / personal use license?
