One of the best things I ever learnt was to make my own unattended install with vLite. I put my base copy of Steam, LoL, nVidia drivers, Chrome (and signed in to get bookmarks and PW etc as soon as I use it), remove IE, Flash, adobe reader, DazLoader. Then I make it into an ISO then into a bootable USB.
I followed some piss easy tutorial I found on the net ages ago and I've used it for maybe 18 months now and have slowly been updating the ISO. Sure, everytime I reinstall I need to update a few things. But it's still a shitload better than starting from scratch.
