I have quite a respect for Paragon software and Giveaway of the Day is offering this as a freebie for a time-limited offer. It comes in 32bit and 64bit versions for Win. Unlike a lot of their giveaways the registration is done on the Paragon website so I suspect the keys provided will not be time-limited if you need to reinstall. Among other things it will allow you to create a portable/virtual version of your system (if you have a big enough usb drive). LINK:
