The developer of Process Manager For Windows claims that with this app "your life will be easier than it was ever before". That may be an exaggeration, but this is a really useful windows application that can improve your desktop space management, as well as giving you a quick kill button for any application.
When you run Process Manager For Windows, right clicking on the system menu tab of any program will now give you extended options like the aforementioned kill button. More interestingly, it allows you to set the transparency of any application, keep in 'always on top', hide it, hide all other applications, and best of all minimize to the system tray.
Process Manager For Windows uses very little RAM, so it won't cause you problems when you're already running lots of programs. While you can of course kill programs with task manager, it's much faster on the right click menu. The minimize to tray option is nice as it gives you more space on the system menu - great for something you have running all day in the background like Outlook.
Process Manager For Windows is a surprisingly useful free application, that really can improve your life in Windows.
