iTunes is a beast. It does a lot of things- but sometimes you just want a music player.
On my work box I wanted to install iTunes as light as possible.
The first step is to download install file from Apple. Save it to a known location.
Use a program like 7-Zip to unpack the downloaded EXE. It will contain more than half a dozen sub-installers.
Copy the following installers to a different directory:
Start a command prompt and change to the directory where those three installers are.
Run the installers in the above order this way:
The installers will put a QuickTime and an iTunes shortcut on your desktop. Unfortunately, there is no way that I have found to run iTunes without QuickTime.
The first time you run iTunes it will complain about not having Bonjour and being able to share music. I think this is a good thing in the work environment. It will not complain after that.
There you go, an install of iTunes that is as light as possible. I can download podcasts, add music to my library, and create play lists.
