Hi, TabletPC binaries are already within XP SP2. So if you have corporate license agreement with MS, just call your MS TAM and ask for TabletPC key. It's free of charge and really that easy, I have done it Myself. MS states: ================================================= To obtain a volume license key (VLK) for Windows XP Tablet PC Edition 2005, contact Microsoft directly and request the VLK. In the United States, the telephone number is: 1-888-352-7140 ================================================= For additional information: http://www.microsoft.com/technet/prodtechn...y/sitpcdep.mspx Regards Ted
