My computer was stolen night of Christmas and the police were called.

I'll have the report sometimes this afternoon - I have the product key code (windows 7).  Can I use the same code product key for an old computer (windows XP version)?

Hi harver01,

If your copy of Windows 7 has been the retail (non OEM), you can use it on another computer.  See the following article regarding lost software:

In addition, please see the following information about how to enable replaced once:

I hope this helps!
