Cannot establish secure connection to Apple Store
I've tried all the solutions I can find to no avail, but cannot seem to establish a secure connection to the iTunes store. No error code just a blank iTunes Store screen and a never ending attempting connection. Some of what I've tried:
* Date and time correct
* SSL and TSL checked
* No proxy and tried to check and uncheck auto detect settings
* Used Autoruns to be sure no other LSP providers
* Ensured Windows Firewall has iTunes fully allowed (even reset Firewall to default and then reallowed it again)
* Removed and/or disabled all security software to test for possible blocking
* Reset Winsock and rebooted
* I CAN reach secure sites in my browser just not in iTunes
* Removed iTunes, Quicktime and any other Apple related items I could find with RevoUninstaller to look for leftover entries, rebooted and reinstalled (several times)
* Cleaned all cookies, caches and old registry entries
* Machine is free of all malware
This only happens on one computer so I know it's not my account. It happened out of the blue (well, I'm sure it was related to something...a Windows update, an update of something....but I didn't associate it at the time so I do not know what). I know another person who had the exact same symptoms out of nowhere and has very different software from me (and a totally unrelated account to mine) so I suspect a Windows Update but I don't know which one.

When I open iTunes it takes a very long time to load, system becomes sluggish, and then when it finally does load, it simply will not connect to the store and it will not recognize any iPhone or iPad I try to sync. When I run the diagnostic the only information it seems to contain that is pertinent is that I can't establish the secure connections. In Safe mode iTunes will start more quickly but since I cannot start Apple service in safe mode I cannot connect to the iTunes store that way. (I have however, disabled all but the most essential startup items and the long load in normal boot still remains).
I'm at a loss. I've Googled and searched the forums here and tried every plausible thing I could find but nothing seems to work. Any further ideas are welcomed. I was going to try an older install of iTunes but older versions won't read a library created in a newer version. I would really like to sync some new items to my devices and since the computer won't sync to the cloud as it can't log in - I'm kinda stuck at the moment. It's really frustrating. I'll be glad to post diag logs if anyone things it will really help.
Many thanks for any additional ideas!
