Thanks for the elucidation Galway,
I appreciate that, but the reason I want to use XP is not because I'm big fan of it. I'm sure that others are not, too. Because of my job I need to use older version of other software and it can't be run in newer Windows. That's why I'm forced to use XP in order to work with it. But my old computer crushed and the new one I bought supports Windows 7 and 8. I installed XP on it, but I need drivers to use all features as well as the software I need.
