Decrpify
One thing (among many) that I like about Win7 is it's good on-board back-up and recovery routines.
I tend to buy PC's from Dell in bulk, and while one batch will differ from the next, I can safely spend a day decrapifying a PC and getting it up to full running order with everything I need on it, and all the rubbish I don't need off it. Having done this I can take a native system image of the, now perfectly configured machine, and spend no more then a couple of hours re-imaging all the other machines in the batch. Barring machine name changes prior to plugging in to the network, they're ready to go and bloat-ware free.
It also means I've got a nice clean install image if, in the future, I need to start again from scratch because of systems problems. Anything software related that I spend more then 1/2 an hour trying to fix without success, I just format the disk and reload the image. Saves me LOADS of time.
