Hello,
I have an IBM thinkpad laptop, and it has windows 7 installed on it, and I was wondering, it has a sticker on the back saying something about windows XP, so I think it had XP installed before,
if I install XP on it, will it perform faster? Have better performance? Loading things better, not lagging and overall be faster...
So, should I install XP or leave it as it is, with Windows 7?

Thank you.
