Need to run Windows XP on your computer, but don't want to reformat your hard drive to install an operating system that others now are not using. This is where MyPocketXP becomes beneficial. Your not only capable of running the operating system via USB but you can also save it's settings. No need to worry about viruses because it's a virtual operating system. There are so many uses for this that I can go on for days. But the best thing about it is that it's portable.
