Q: just downloaded 10.5.  It gives me a blank screen for the itunes store.  No error message.  Internet connection fine.  Have checked firewall.  Any ideas?

netsock reset did not work here, still black page and AppleMobileDeviceService.exe is hogging 100% cpu usage on one core... thnx apple. need 10.5 to get ios 5 but in return im burning cpu and unable to enter the store.

Did you see solution for Windows 7 and similarly Windows XP from JerryFromKrakow at: iTunes for windows - App Store's blank page - final solution

1. Fixed the itunes blank store window.

2. Also fixed the backup/sync problem.

3. Even solved the AppleMobileDeviceService.exe high cpu problem.

Please reply after trying Jerry's Windows 7 fix.

Please reply to let others know what got fixed or did not get fixed by this.

Yep

Don't use the previous version of Apple Application Support with 10.5!  It's not compatible with the newer version so although it worked with 10.4, it doesn't work with the newer one and you'll end up making things more complicated.

Thanks japiohelp, your solution worked perfectly...I had deleted all apple products, folders, etc, to no avail. 

Running netsh winsock reset from an admin cmd windows did the trick....

Oh my god!!!!!!!!

"netsh winsock reset" It worked

For Window XP ---- Go to Acesssories --- Right click on command prompt ---- Run vista executable

and then type netsh winsock reset

enter

success

reboot your com

Yeah!!! I can access to itune store and back up my iphone now....

iOS5  I'm coming ^__________^

Thank you very much...

Japiohelp,

This fixed my problem! Thanks.

I was getting the blank ITunes Store page, even after installingITunes v10.5.  Running the netsh winsock reset command fixed my issue.

I was also having an issue where any backup of my IPhone would start and hang.  After running the command, its working great again.  I was able to install iOS5.

Again,  Thanks for the great help.  Glad I found this post.

Thank you, thank you, thank you - this worked. Cannot thank you enough!!!

I've tried the winsock reset twice now amd still no iTunes Store.  It let's me see my account details but is not much use for anything else.

Thank you so much, japiohelp.  I tried so many suggestions.  Yours is the one that finally did it for me.  Now to wait for my iPhone 4S when it comes out later today. 

Kind regards.

You guys should be happy that 10.5 installed...I can't even get that to work FFS...:(

Wow, just turned off Ad-Aware and I'm now getting the store....  sheesh!

The netsh winsock reset solution didn't work. I'm on versions 10.5 of iTunes. Yes, I did restart. I did it all over again just to see if it would work & again restarted with no fix on the store.

I first hit this issue when I downloaded 10.4 only less then 2 weeks ago. I didn't do much with it other then to get frustrated by it. I was hoping 10.5 had been fixed so was glad to do the download. Nope, it wasn't.  Still frustrated but a friend pointed me to these threads and had some hope. Tried to stay at 10.5 & get it to work as I have an iPhone on order (get it around the 24th). Maybe there will be a fix before then. 

Got It Working!!!

I tried all the windsock reset ideas on various threads here but none worked. I finally uninstalled Spyware Doctor and now iTunes store is coming up. I still have Norton running. I've always used both as from experience Norton doesn't catch everything that it should. Anyway, if the windsock resets don't work try uninstalling like I did. Just don't leave yourself wide open.

japiohelp - I could kiss you!

Spend FOUR DAYS on pinning down the problem until I found your advice here.

yaaaaahoooooooooooooooooo !!!
