Before Windows 7, the consoles seemed to be handled entirely by the csrss process. If you started bash directly, there was no other visible process involved. Starting with Windows 7 there's suddenly a "conhost" process for each console. Just as a side note, Windows 7's new conhost also broke the method to start an invisible console by creating it in a new, invisible WindowStation, and that still hasn't been fixed in Windows 8, despite my bug report during the W7 beta...
