Hello, welcome to Windows 7 Forums :)

Unfortunately, if you don't have the product key written down anywheres, there isn't much you can do.

You could always do a factory reset, then use the Windows 7 Upgrade path again if possible, or contact HP support or Microsoft as they could offer support in re-validating or getting you a new product key.
