Know every version of iTunes installed on your machine? I do.

I've installed the following versions of iTunes on my machine:

  • 7.0.2.16
  • 7.1.1.5
  • 7.2.0.35
  • 7.3.1.3
  • 7.5.0.20
  • 7.6.2.9
  • 8.0.2.20

Know how I know that? It seems that all Apple software on Windows (iTunes, QuickTime, and Safari, at least) leaves their traces in the following directory: C:\Documents and Settings\All Users\Application Data\Apple Computer\Installer Cache\

313 MB of space is what I would recover if I deleted all the folders they created. Yikes.
