Look on the bottom or inside the battery compartment for a windows 7 coa activation code.
If you find one, borrow or download a stock windows 7 install dvd and use that to install windows 7. The coa activation code should activate your new install.
While you are at it, consider replacing the hard drive with a ssd. It will make the performance magical.
