How do you upgrade to pro? I installed home because I was thinking of using my existing win7 key, then though better and activated the other way (because the old computer is still in use by mum - she gets my castoffs lol). But I would have installed pro if I knew I'll want to keep the win7...

What do you mean "can"? It can only be turned off for a month, max, then they force update it for you.

Wait I could have used my (legit) win7 key for 11?

I actually had to start eating more fat because the "normal" fat diet (not even low fat at that) I had was making my stomach ache. Started putting more fat on everything and it's all good now. I'm even actually dieting and losing weight - cut out a lot of sweets instead and I'm eating less of everything. But with more fat.
