I use different user accounts on my laptop to segregate out my work, so I can keep personal use separate from work and hobby stuff. I have a single iTunes account and three Windows user accounts, and I'd like to be able to simply open iTunes when logged into any of my three Windows user profiles and view the exact same library and playlists. I know I can log into each one individually to get the iTunes store to be the same (wishlists, etc) but I want the local Music and Video libraries and playlists to all be the same as well. And I'd like to be able to buy something while logged into any of those Windows user accounts on a whim, and it will still show up when logged into the other Windows user accounts as well.

Basically, one iTunes library for the machine, and any of my Windows profiles can access the same library at any time, and add music to the library from the iTunes store or otherwise at any time and it will all be viewable the same way from any of my other Windows accounts.

I couldn't seem to find anything on Google, but maybe I just didn't type the right keywords. :(

I'm running iTunes 9 on Windows XP.

Thanks for the help!
