For enthusiasts and IT professionals maintaining legacy systems, hunting down separate DVDs for Windows Vista Home Basic, Home Premium, Business, Ultimate, and the various 32-bit (x86) and 64-bit (x64) editions is a nightmare. The solution is the Windows Vista All-in-One ISO —a single, bootable image containing almost every Vista edition and architecture. What Is an All-in-One (AiO) ISO? An All-in-One ISO merges multiple Windows installation sources into one file. When you boot from it, you see a single menu allowing you to choose exactly which Vista edition you want to install, rather than juggling five different discs.
