Congratulations on upgrading to Windows Vista. The retail package product ships on DVD with 32-bit edition software, but two forms of alternate media are available to help meet your specific requirements:
32-bit CD: If your system features a CD drive but no DVD drive, you can order Windows Vista on CD-ROM. The installation files span multiple discs, so unattended installations are not possible.
64-bit DVD: If your system features a 64-bit processor, you can take advantage of its advanced design by ordering 64-bit software media. You’ll get the same interface, features, and functions, but you’ll get them in an operating system that takes advantage of access to vastly more memory. All installation files are on a single disc. Please note that 64-bit media is included in the box with the purchase of Windows Vista Ultimate.
The 64-bit version of Windows Vista is not for everyone. Please confirm that your system, applications, and devices are compatible with a 64-bit edition of Windows Vista before installing. Learn more about the 64-bit editions of Windows Vista.
You can order either of these alternate media for a minimal fee, including shipping and handling. To order, you’ll need to supply the 25-character product key that came with your purchase.* You’ll find the product key on a yellow sticker on the back of your DVD media holder.
