It was easy for me as well. you don't need special knowledge to install it. but if you try it on your main computer that you need to carry out your daily activities, then come across an issue such as your printer does work when your printer is a necessity, or the internet doesn't work because the generic driver for your LAN is not available, then you'd have to deal with those issues, or you'd wanna roll it back to XP, but I'm not sure if the poster feels confident about trouble shooting driver related issues, reinstallation of XP, etc all that. And there's no support by Microsoft this time. I think it's worth a shot if they have a SPARE computer, if they are lucky, it'll be "very" easy.
