First is Lita. It's an Adobe AIR application that's a nice friendly graphical front-end for SQLite files. I use SQLite files in my own games to hold the settings and high score tables, and Lita is the perfect thing to check the files to make sure they look the way I intended.
Next is CCleaner, which is a dandy little gizmo that gets all the crud outta your system without (thus far) screwing anything up. It actually does quite a good job.
Third is something you already know about. Notepad++. Whether you just want something better than notepad or you wanna do some heavier stuff, it'll handle it.
Last, and least related, is Hulu Desktop. It's not programming related at all, but it's quite a nice thing for watching lots of TV on your computer. Between this and Windows 7's "finally it's good enough" Windows Media Center, you no longer need cable TV.
Only complaint is that Hulu Desktop is a standalone thing and it refuses, REFUSES, to integrate with Windows Media Center (unlike Netflix, which loves WMC just fine). While it's not perfect, somebody put together a little hack here that at least gives you a Hulu icon in WMC so you can switch to Hulu without going to the Start menu. Good if you have a TV.
