iTunes 10.5 hangs during iPhone 4 sync

I tired that and all I got was " the reqested operation requires elevation <run as administrator>

How can I go around this?

Thanks a lot !!! So lucky to find this post. Worked perfectly on Windows XP after having tried everything!!!

Best post ever!!!! How did you find out this?

It worked in my windows XP!! Thanks a lot

Thank you!! After 3 evenings of trying to fix this, at last a resolution. It worked on Windows XP. So thankful to have things up a running again.

Pinocchio85, go to c:\windows\system32\cmd.exe and right click and select "Run as administrator". Then complete the steps.

Brilliant! Worked like a charm with iPhone 4 ios 5 on Windows XP! Saved me from throwing my phone and computer out the window! Thank you, thank you, thank you!!!

Finally found a solution to my problem:

That did it! Thanks!

Thanks!

'netsh winsock reset' did it after trying for 3 days. You're a life saver. 🙂

This even helped me. Thanks alot.

Just one question though: do I have to do this stuff every time? Cause when I need to connect it again after maybe a week, I´ll have to do this step once again.

Actually I didnt have the problem of iTunes freezing durig the sync, it rather freeze when I connect my iPhone and iTunes is starting up. (In settings I´ve made the change not to sync automatically when I connect the phone, maybe that´s why it freezes on startup)

This corrected my problem as well! I have an iphone 4 with iOS 5 and windows 7. Same issues of the CPU running at 100% and not able to do a backup at all! Thanks for the help guys!

It seems that the standard repsonse is "have you tried switching it off and on". The unfortunate thing is that when the Apple is working it appears bullet proof. However when it does not work then you basically have to fend for yourself. I have doubts that iTunes etc interface is written with any intelligence, it often asks you to do three different things at once: backup, update and transfer, that you know will conflict, but you trust them and click the OK button. Don't do it. I also recommend restarting everything before any updates as this seems to make them go smoother.

I had same problem as others, netsh winsock reset wouldn't work. Tried all kinds of things for several hours, then I just re-installed iTunes over top of the existing installation (did not un-install anything) and it worked! I installed 10.5 build 142 on top of 10.5 build 142.

As per Frank above the netsh did not seem to work. However waiting a long time does. It seems the backup is not to the local computer but into the "cloud" and it then restores from the "cloud", this is why it takes so long i am guessing. However maybe counting eggs to soon as has not restored yet. Was considering waiting till 5.1 and they had the bugs out. Do not like being the vanguard. Also once again iTunes wanted to apply changes half way thru the process, i selected "do not apply" goodness knows what would have happened if i had selected to apply them? I think Apple and other providers rely on a stable and fast internet connection to achieve their aims, which unfortunately is not always the case. I am also concerned with Apple having a backup of my phone, but i guess i would have contracted that concern away, when i clicked the I agree checkbox. At least when it is restoring it gives you an idea of how long you have to wait, even though its been stuck on 48 minutes for the last 20 minutes.
