I've been reading about and attempting to create my own "Windows 7 All-In-One" custom DVD. I've learned that you can put both 32-bit and 64-bit images on one DVD and choose which to install. I've actually done my own and tried it and it seems to work great. But my question at the moment is simply: 1)Did Microsoft ever release a "Windows 7 DVD" that contains both 32-bit and 64-bit versions of their flagship OS "Windows 7"? 2) If not, why wouldn't they to save, at least a few pennies, on bundling 2 DVDs in every "Windows 7" retail box? I know that the retail edition of "Windows 7 Ultimate" contains 2 different DVDs. Both 32-bit and 64-bit editions. This just seems wasteful. But I keep an open mind. Maybe there was a good reason for it. The cheapest I have ever bought a DVD is .16 per disc. So, .16 x millions of extra DVDs would have bought me a nice new home.
