How to deauthorize a dead computer for iTunes

Or yet another in the set of things you may need to do when your laptop gives up the digital ghost.
Apple does not hide the information on how to do this, but neither do they make it all that obvious to find. Here is the direct link to their support page on deauthorization.
In essence – on a machine with iTunes, go to the iTunes store, login with your account (note, if you are using a friend’s computer be sure to log out of their account first), select the “view account” option, then there will be an option to “deauthorize all” – select this and ALL of your authorized computers will be deauthorized.
This means that if you have to take this route, you will need to then RE-authorize each of your other machines.
A better solution – if you have the chance before your computer dies (or you recycle it/sell it/give it away) be sure to open up iTunes on that machine, connected to the Internet, and deauthorize JUST that machine.
