When I first purchased windows 7, I was running windows xp so I purchased an upgrade key. After formatting and installing windows 7 it became clear that Microsoft wasn't going to let me just use an upgrade key after a fresh install. So I began to browse the web in search of an answer, Not long there after I had my solution; A registry edit, and a command prompt script. After I performed the operations i decided to hack up this little tool that performs the patch "automagically"
This little app simply edits the registry to change the install type from "full" to "upgrade", and then calls a VB scripts from the system directory that rearms the system, the same functionality that allows you to change your product key without a reinstall if Microsoft blacklists your system and sells you a key (these two concepts are completely different, it just uses that innate functionality).
it's far from pretty, never intended it to be, Some programmers are so proud of their little patches that they spend more time on a theme and background music than they do on the patch itself. This is just a simple dialog with a "Enable Upgrade key" button. But it works, so I'm satisfied.
