New installation of iTunes on Windows 7 64 bit hangs

Question

I just installed iTunes 9.0.3 (64 bit version) on my Windows 7 (64 bit version as well) PC (Core i7). The installation seemed to work fine.
But from the first start of iTunes, it has very slow response times and I can't do anything like browsing music or synchronizing with my iPhone. If I click on the menu bar, it takes 30 seconds until it pops up. To exit from iTunes, I have to kill it with the task manager.
The installer wants to put iTunes to C:\Program Files (x86)\iTunes. I expected - as this is a 64 bit version - C:\Program Files\iTunes being the appropriate location.
Any ideas?

Not even the built-in Windows Firewall, Tofswi?
Oh yes, you are right. As it silently works in the background (what I like), I completely forgot about this one. It is activated with default settings. I did not touch it since installing of Windows 7.
I took one more try and reinstalled iTunes. And it works - regardless of whether the firewall is activated or not. So where's the problem then: It's my iPhone (3G). When I plug it in, iTunes immediately slows down. Then I remove the iPhone and iTunes comes back to normal operation. In my case, the firewall does not have any influence on that.
As I can see in other threads like http://discussions.apple.com/thread.jspa?messageID=11204685&#11204685 I'm not alone in this matter.
- I checked the iPhone USB driver: It's up to date and I can access the iPhone by the Windows explorer)
- I tried to give iTunes time "to get accustomed" to the iPhone: Sometimes iTunes crashes completely, sometimes there is an unknown error (different error numbers, e. g. -6999)
- Then I happened to be the lucky user being allowed to click on "synchronize": Unknown error again, but iTunes always seems to proceed a little bit - it's confusing.
- Then a deactivated synchronizing of all (applications, music etc.) but the contacts and clicked on "synchronize" again: It's quite interesting that iTunes complains about not being able to download Wikipanion from the iPhone as I just told iTunes not to synchronize applications...
After all these steps the contacts of iPhone had been transferred to the PC, fine. And I could not start the applications on my iPhone anymore, not very fine. Every application I touched started up and closed again immediately. I remember: Reinstalling all the apps will help, great But wait, as I already know, this is a problem of the DRM. I only had to update one of the installed apps through the app store directly on the iPhone. Then it worked again. Installing a new app should help as well.
I like the easy handling of the iPhone. But iTunes with iPhone on Windows 7 is an impertinence. It's really not the quality I expect from Apple.
b noir, thanks a lot for helping.
I for myself am going to take a cup of tea now. And perhaps I will sink into contemplation about the time I spent in the old days to transfer some addresses from one to another datebook by pencil compared with the time I spend today to debug modern software.
