OK, so my desktop spectacularly crashed yesterday. I have tried and tried and failed to re-instal ubuntu which won't have it, despite a new HDD.
Anyway, I have been liking Windows 10 on my laptop so I have managed to install it on the desktop with no problems. I installed it using an iso image disc downloaded courtesy of Microsoft.
I installed without a product key. My question is that if I purchase one of the numerous keys advertised out there on the net, will they work? They seem to come in at all sorts of prices, £10 to £30, or £200 odd from Mr Gates himself.
I was considering buying from here:

Are there any real downsides?
Thanks all
