At its core, the Windows 7 Professional ISO is a sector-by-sector copy of the original installation DVD.

What distinguished this ISO from consumer versions was its inclusion of three critical enterprise tools: , EFS (Encrypting File System) , and XP Mode .

The legality of downloading these ISOs is murky; while Microsoft no longer sells keys, they have officially archived the ISO for developers via the "Windows Developer Center," though standard users are directed to upgrade. The ISO file allowed businesses to standardize their
