other fab programs that are absolutely 100% free:

recuva - accidentally deleted something in the recycling bin? recover it back with this program!

speccy - tells you the specs of your computer, among other things

defraggler - defrag the SHIT out of your hard drive and clean it right up

This is a great post what makes it even better is that most of these you can get from Ninite which will download and install the latest versions of all available software ALL AT ONCE without you having to worry about adware or the annoying clutter (toolbars, changing your default search engine) that sometimes comes with their individual installers. So, yeah. Have at it folks.

For posterity.

Good lord this is awesome.
