A lifesaver! First place I go to after a fresh install of Windows - pretty much everything you need to turn a useless lump of metal and plastic into a useful workhorse is just a couple of clicks away here.
Quite a handy site if you are having to download various essential software for other peoples computers, basically lets you create your own exe that will install various software, saving you time going to each of the vendors site.
Absolutely amazing. Saves so much time and makes reinstallation so much easier on the head. Would recommend to anyone trying to get many necessities installed.
Very useful for re-downloading/installing open source programs in one swoop without having to do each separately. Highly recommended for those of you upgrading OS.
