In (re)installing Windows 7 on different systems, finding the right disc is just as painful as its predecessors. Fortunately, I found some things that deal with that, as well as restore some old features.
* How to make a Windows 7 All-In-One DVD
* Tools to change a Windows 7 ISO to whatever edition you need
* Windows 7 DreamScene
btw, if you dig around http://code.kliu.org/, you'll also find the Notepad2 installer that replaces Notepad, and an "Open Command Prompt" menu addon.
