Microsoft Treats Testers to XP Pro x64
Thanking testers for their hard work debugging Windows XP x64 Edition, Microsoft will be offering beta participants a full retail copy of the 64-bit operating system in downloadable form. Windows Beta Team officials said product keys and download links were being prepared, and would be sent to testers within a few weeks.
"As a small measure of our appreciation for your help in testing Windows Server SP1 and Windows x64 on the Technical Beta, we are offering active participants a complimentary full copy of Windows Professional x64 Edition," read an e-mail sent to testers." This will be done as a downloadable ISO file only, but will be a licensed copy of Windows Professional x64 Edition. (i.e. not an eval copy)"
