Hide programs (such as Skype) from Windows 7 taskbar
Running the latest version of Skype on Windows 7 (starting with Windows), Skype integrates with the Windows 7 taskbar, staying "open" all the time. That is, when I click the top right "x" on the Skype window, it minimizes to the taskbar rather than actually closing the window and just staying open in the tray. I want to disable this integration with the taskbar such that Skype is only open in the tray area, mostly to get it out of my Alt+Tab list. Is there any way to do this? I googled around, but I couldn't find anything - probably partly because I don't know how to phrase the query.
