I've taken a liking to the positioning of the Ubuntu titlebar buttons being on the left, and saw there is a program called Leftsider that does it on Windows 7. However, I don't want to use a program to do that for me, and given that I'm confident with mucking around with the registry, I'd like to know where the reg entries for the Titlebar Button positions are. Besides, doing it manually rather than automating the process gives me a chance to learn more about Windows!
