With those symptoms, I'd try the following document:
(If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)
I have been working on this problem (iTunes for Windows) since April 2012 and finally got it working. I have gone through all the suggested "advanced" trouble shooting procedures with no luck. I even tried opening a work order with them which was a waste of time because they had me retry everything I had already tried and never read my responses. I am attaching all my notes on what I have tried since the beginning. What I think was the issue all along was .net 4. The fix was listed in 12-03-12 where I removed everything, including .net 4, installed an earlier version back when iTunes was still working. I am now running version 188.8.131.52 and it is still working, Good Luck!
- Updated to latest version of iTunes 184.108.40.206
- Windows had put back .net ver 4
- Did repair of .net 4 from control panel, add/remove programs
- Did repair of iTunes from control panel, add/remove programs
- Went to store tab, review my Apple ID, it displayed my account info
- From there went to the music icon, selected one of the drop down options
- Store displayed all the music in that category
- Removed iTunes, all the apple crap, bonjour and QuickTime
- Rebooted and reinstalled an earlier version of iTunes ver 10.3.1 9 (still didn't work)
- Removed .NET (it was ver 4)
- Rebooted and retried iTunes, still no iTunes store.
- Removed iTunes ver 10.3.1, rebooted and reinstalled iTunes ver 10.3.1 with no .NET stuff at all and it worked.
So iTunes didn't need the .NET stuff to work but it must have been corrupted in a way that won't let it connect to the iTunes store correctly.
Next I am going to upgrade to the latest version without .NET to see if it still works. If not I will fall back.

This Is the real solution i get to know.
Being a computer engineer, I did almost everything i was knowing and all the things that diff forms used to say.
But in the end, by removing a download manager I was having it solved the problem.
