So yeah, I downloaded iTunes 10 as soon as it was available earlier this week. Early adopter I am. Not such a good thing this new iTunes is. Not only is iTunes 10 just another bulky application, it no longer works with Windows Home Server. I had already upgraded when all the WHS sites started talking about the incompatibility. What’s a boy to do? Restoring was my only solution. Seriously.
DON’T DO IT! DON’T UPGRADE.
Of course, if you do not use the HP MediaSmart Server shared iTunes functionality then go ahead.
Why not iTunes 10?
After iTunes 10 installed and did not work with my WHS, I tried uninstalling iTunes 10. The uninstall was easy, and after 30 minutes of trying to find the download of version 9, I thought I was going to be ok. WRONG!
Not only does Apple make it impossible to FIND an old version of iTunes, the new iTunes 10 updates the “itl” database file so you cannot use an older version of iTunes.
AGAIN, once you upgrade to iTunes 10 you cannot go to a prior version! Ok, maybe someone will develop a hack but for now you cannot go back! Flippers.
I had to Restore to a prior backup. This PC is my main garage PC so I do not leave it on all of the time. I had to backup to 08/29/10 so I made sure any files I had were moved to the Shared Folders BEFORE the backup. The 7:42 backup was AFTER I had upgraded to iTunes 10.
Welcome Back iTunes 9
It had only been a few days but I missed you. Don’t ever leave me again.
Conclusion
iTunes 10 is not worth the upgrade right now. I will use a test PC and keep up with the updates and post when it is working with Windows Home Server.
See you next Friday night,

I've ordered an Apple TV, and was hoping to use it to stream from my WHS. If iTunes has to be running on the WHS then it's a right pain.

Here's a link to itunes 9. But version 10 will mess up your database, (nuts)
Here is a fix, http://appletoolbox.com/2010/09/how-to-downgrade-… if you mess things up, you can always do a PC Restore.
