Windows App Store / apt-get for Windows
I don't see myself switching back to Windows, but these could turn out useful at work or with family. Windows software installation is no fun after getting used to Debian Linux or macports. These tools together could be a poor mans apt-get for Windows: PcDecrapifier - To unload the unwanted preloaded software. Ninite - To easily load all the common software. BaseShield - An alternative to Ninite, perhaps.
