Lot of people’ve started installing Windows 7 with intentions to activate when their product key arrives in October. It’s probably worthwhile to install the same version you’ve preordered. Because, by default, original copies of Windows 7 does NOT allow you to choose a version during install. Having said that, one can easily workaround the problem; until RTM, the Windows 7 ISO that Microsoft distributed’re labeled as “Ultimate”. Even though the install image “install.wim” in Windows 7 still contains four versions, one version’s automatically installed determined by a file called “ei.cfg” in the “sources” directory on the install disk. To get around this limitation, simply deleting the “ei.cfg” file’ll allow you to choose a version to install. Note: This hack does allow you to switch between versions of Windows 7 to install, it doesn’t allow you to install other variants of Windows 7 like Windows 7 E or Windows 7 N. You’ll have to download a new ISO image for that.
