Microsoft: Clean installation from Windows 7 Upgrade Disc Is Illegal

Since the official release of Windows 7 last October 22, there have been various posts across a variety of social media engines showing a “hack” that a Windows 7 Upgrade disc can also perform a “clean” installation of Windows 7 OS on a blank drive from a technical perspective.

Eric Ligman from Microsoft posted in his blog that although it is doable, “technically possible” does not always mean legal.

Eric further gave some basic facts about it:

1. When you purchase software, you are purchasing the rights to run the software according to the terms of the End User License Agreement (EULA) that comes with that software.

2. When you install that software, you are agreeing to the terms included in the EULA you purchased.    a. For instance, in the Windows 7 EULA it states, “By using the software, you accept these terms. If you do not accept them, do not use the software. Instead, return it to the retailer for a refund or credit.”

3. When you purchase an Upgrade license, the included EULA states that you must already own a qualifying full license to upgrade from in order to use the Upgrade license, hence the term “Upgrade.” a. For instance, in the Windows 7 EULA it states, “To use upgrade software, you must first be licensed for the software that is eligible for the upgrade.”

To clearly illustrate the scenario, here’s a graphical representation of what it means:

Well, if you’re planning to install Windows 7 on this “hack” (as what they called it) method, just make sure that the authorities won’t caught you in the long run. :p
