How To Make A New PC Feel Like Home

I just received my new PC. I'm very excited, with a little tinge of sadness - this is what I've treated myself with after my dad's death earlier this year (sorry this keeps coming up in supporter posts by me). And so, rather in tribute to him, I was a little excessive. I spent more than I needed to. So I confess to having bought myself a setup with an i7 6700, a GTX 1080, and most ridiculously, 32GB RAM. Yeah, I know. Anyway, in setting it up it occurred to me that I could be useful, so here are some genuinely helpful tips for getting a new PC (or a new install) nice and comfy as quickly as possible.
