Spyral Out

This is a fix for slow Zune marketplace on Win 7, I have tested this on my Win 7 64 bit. Marketplace works fine on my Vista 32 bit and xp 32 bit. You can try this for your Vista 64 bit too. You can find users reporting on this forum http://forums.zune.net/2/8/526815/ShowPost.aspx

The Fix
Turn off Automatically detect LAN settings in your IE.
Steps

1. Open IE
2. Click on Tools–> Internet Options
3. Click on “Connections” Tab
4. Click button “Lan Settings”
5. Un-Check ” Automatically detect settings” (this is/was set by default in my Win 7 installation)
6. Restart IE and Zune (if you had it open)

I found an article for slow saving of documents in SharePoint from Windows 7 client and this was the fix and thought these were related.
