iTunes
7.2 first oldest version of iTunes to function (probably because it's the first with Vista support), doesn't connect to iTunes store, supports Audiobooks (needs to be checked in Preferences)
7.4 has different GUI (selected menu is blue instead of dark grey)
7.2.0.35 does not have high quality AAC encoder (at least not as a preset, 256kbps is available under Custom) and GUI isn't updated like 7.4 where selected menu is blue
7.2.0.35 only uses 26MB of memory! (no, 50MB after iPod use?)
Troubleshooting
Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
remove items from add and remove programs
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products
also remove manually all folders, Common files application support etc.
iTunes 7.4 CD configuration error on startup, just create an empty folder named "CD Configuration" in the iTunes folder in program files
I've spent a lot of time on iTunes in my life
