How to Deauthorize a Dead Computer on iTunes

Apple lets you authorize up to five computers to download and play your iTunes Store purchases using your Apple ID. You can deauthorize a computer as well, thus freeing up room for a different computer to be authorized. If one of your five authorizations is a dead computer you can no longer access, you can still deauthorize it -- but you must deauthorize all five authorized computers at the same time. Apple lets you mass deauthorize your computers once per 12 months.
