Apple software on Windows: May see performance issues and blank iTunes Store

http://support.apple.com/kb/TS4123

 

Symptoms

You may notice the following symptoms on your Windows PC after installing the iCloud Control Panel, iTunes 10.5 or later, or Safari 5.1 or later:

• iTunes is slow to respond.
• Windows is slow to respond.
• iTunes stops responding when backing up or syncing with an iPhone, iPad, or iPod touch.
• Some processes installed by iTunes are using up a lot of resources in the Windows Task Manager.
• Connecting an iOS device causes iTunes to quit unexpectedly.
• iTunes Store displays an "error 0x80090318" alert.
• iTunes Store looks empty and white as shown below:

 

 

Resolution

The cause for these issues is a program that monitors the Winsock protocol for Windows conflicting with Apple software. These programs usually use a Layered Service Provider (LSP) that can help identify the particular program installed. The programs that monitor this protocol have a variety of purposes, including security software, content filtering, and optimization of network traffic.

 

To find the LSP:

1. Download Autoruns for Windows from Microsoft
2. Look for Autoruns.ZIP and open the compressed folder.
3. After reviewing the contents and the license, drag autoruns.exe to the desktop.
4. Open Autoruns.
5. Click on the tab that says Winsock Providers.
6. A list of items should appear. A column showing the publisher should be available.
   
7. For items other than Bonjour, which is from Apple, check with the publisher for updates to resolve the conflict between their software and Apple software.
8. If the publisher is unfamiliar to you, you may be able to use the table below to find out more information about the origin of the modifications to Windows.

Some of the publishers and programs that are known to have versions with a conflict are listed below:

• Once you've identified the third-party software that installed the LSP, you should check for updates. If the software is your security software, see iTunes: Troubleshooting security software issues for additional information. 
  • Bytemobile is usually associated with cellular data connection software. You may want to check if your provider has instructions to disable or uninstall that portion of the software, such as these instructions from AT&T.
  • Note:  If unsure on the origin of your LSP, you may try to locate vendor information to determine which software is responsible for the non-default value here.
