It is a very general question for a problem that has many answers. Well, programs that you would like to run in the background need to have an option somewhere in their configuration menu or options menu in order to change whether it will be active or not while the window itself is inactive. As far as I know, the only way you can change this manually is for you to be a programmer and do this yourself somehow (I am learning, but I have no idea as of now).
So, depending on what program it is you want to run while inactive, you need to look through the configuration/options files, looking for options such as "Pause program while inactive? ". That's about it, though.
Some of the uncommon keyboard shortcuts in Windows XP and Vista are using shortcuts to minimize and maximize a window. To minimize all the windows you can use the keyboard shortcut Windows Key + M or you can also use show desktop (Windows Key + D). I prefer the shortcut for show desktop as you can press it again to show the last active window.
To minimize only the active window, press alt + spacebar and then press N. Sometimes when you open an application and if it opens by covering only half of the total window size and if you would like to maximize it, you can use the shortcut keys alt + spacebar and then X. Other highly used keyboard shortcut would be to lock the computer.
Use Windows Key + L to lock the computer. You can also set up a desktop shortcut to lock the computer. How to create custom keyboard shortcut to open any application?
