Bests & Worsts Reviews from Amazon

This is Linux. It is also a live boot from portable version with persistence enabled. Your Windows programs will NOT run on this with the small exception of using WINE. That will run SOME of your windows software, but definitely not all of them. Another fun note, you can actually do this yourself for FREE. Linux is FREE and open source. There are many versions that are tailored to run on old hardware--older than your Windows 7 laptop certainly. There are also versions tailored to run on higher-end hardware with all sorts of fanciness in the operating system. Best yet, these are all 100% FREE and will cost you NOTHING except the price of a thumb drive or a DVD to burn it on. If you are looking for a rescue utility, then look into the many Linux versions (and even some windows based ones) that are already set up. All you have to do is put them on a bootable usb or on a dvd/cd. The site you download them from will have plenty of instructions on how to make a usb drive bootable. It's really quite easy and you don't have to be 'computer literate' to do it.
