Why there are no official driver release for windows 7 for this model?
It is become the HP/Compaq way to tell user what OS you should use with the model you have, so if there are only driver officially for Xp release mean your laptop only can be use with windows XP. However they not directly prohibit you to use other OS, but you will need to contatct them for technical issues such as compatible driver and other setting.
