I upgraded my home PC to from normal Win 10 to Win 10 Pro specifically so I can use RDP to log in to it from work to make it look as if I'm working when, actually, I'm pissing about on my home PC*.
I think it cost about £7 with an upgrade key acquired from eBay.
*in my defence, we've had fuck all work for months and, in fact, have now emptied our order book and are shutting up shop. It's been so long doing naff-all it's going to be a major shock to the system in three weeks when I start my new job!
