Windows 7 no longer has “One Disc to Rule Them All” universal installation DVD disc media or ISO image which allows users to select whichever editions of Windows 7 they prefer to install during setup. Instead, each Windows 7 installation ISO or media is specific for a channel and distribution and can be used to install an edition of Windows 7 only.
The one-edition only of Windows 7 ISO or DVD may bring inconvenient and challenges to some people. For example, TechNet or MSDN subscribers will have to use and waste unnecessary bandwidth to download multiple ISO images for each editions of Windows 7. And for people who wants to backup and archive Windows 7 ISOs or DVDs will now have to allocate more disk storage or cabinet space to save and store multiple ISO images or DVD discs, instead of just two – one for 32-bit Windows 7 and another for 64-bit Windows 7. Worse, if user want copies too for allegedly retail, upgrade, oem or volume license editions.
