If you use iTunes and you have two or more PCs in your house, you will likely, at some point, encounter the 5 computer authorization limit imposed by iTunes. There are a number of times when I’ve either replaced my PC or reformatted my hard drive and I’ve forgotten to deauthorize iTunes before doing so. This really is not the end of the world; however, if you do reach the five computer limit, your only choice is to deauthorize all five computers on your iTunes account, which can be a pain because you need to add them back again. This guide serves as a reminder to deauthorise iTunes on your iTunes account before you reformat your hard drive or get a new PC.
To deauthorize iTunes:
- Open iTunes.
- Click Store > Deauthorize Computer…
- You will be prompted that the deauthorization was successful.
That’s it. Now you can enjoy your iTunes account on five fully functional computers at one time.
