iTunes freezes when I click on Edit | Preferences

Have you tried this after re-starting your computer?

I updated my iTunes to 10.6 and my second account had the same issue, I chose Edit/Preferences and iTunes freezes, even though I had closed the iTunes on the first account. However, after a re-start of my computer, it now works correctly.

I am experiencing the exact same issue as doteddy. Additionally, I am not able to sync an iPod on any account other than the first account that is logged in.

For example:

• Boot Win 7 64 bit;
• Log into Account "A";
• I can access iTunes Preferences and sync an iPod Touch without any issue;
• Close iTunes in Account "A";
• Switch User and Log into Account "B" (note Account "A" is still logged, but I have switch over to using Account "B";
• I am unable to access Preferences in Account "B" and I am unable to sync an iPod on Account "B";
• Log out of Account "B";
• Log out of Account "A";
• Log back into Account "B";
• Now that I am only logged into Account "B" I can access Preferences and Sync the iPod Touch on Account "B";

I have spent five hours trying to resolve this issue, unsucessfully. I have tried many solutions suggested by others with similar problems, but to no avail. I have uninstalled, reinstalled, and repaired iTunes several times. I have also tried creating new user accounts and using alternate accounts. The problem doesn't seem to be associated with specific user accounts; rather it is associated with being logged into more than one account simultaneously.

The problem is fully repeatable on my Win 7 64 bit system with iTunes 10.6.1.7 installed.

Note: the accounts that I am using (i.e. account "A" and account "B") have different security privileges. While I don't think this is material to the issue, I mention this just in case.

This is beacuse syncserver.exe is running as the first user. this application is not closed when itunes is closed. Aparently itunes can not use syncserver if it is running under another user context.

Resole your issue by doing the following

Close itunes (if open as user2)

use task manager to kill the syncserver.exe process (running as user1) You may need to hit the button show processes from all users.

Open itunes as user2

I had the same issue, this resolved it.

Thanks, bilbus. I had the same problem on a laptop running Windows 8 and your suggestion fixed it for me.

Doesn't work.

Edit: Went out and left it for a couple of hours, preferences had popped up however upon attempting to open any sub-tabs it froze again.

Having this same issue. Seems like itunes is just really really slow. What did you do to fix it?
