Itunes store error 0x80092013 windows 7

Question

Ok before I start, I've started a new discussion because I want to layout all those things which I have tried to resolve this issue so before anyone posts a "try this" please read what I have already tried.
Symptoms - When trying to access the itunes store a dialog box comes up saying unable to access store error 0x80092103, additionally under itunes 11:04 if you try to run the diagnostics itunes freezes. Additionally the behaviour under an earlier version of itunes 10.6 when accessing the itunes store the error code was 1202 but you could run diagnostics to completion (which reports no errors)
Ok the things I've tried
Earlier version of itunes - as you can see from above I did try 10.6 but same symptoms just different error code
Re-installing itunes - Yes tried removing all instances of any programs which may have even looked closely related to anything apple, cleared all directories from windows explorer, rebooted and installed itunes but the same error displayed afterwoods. (Including appdata directories under [user] )
Date Time - Yes tried the date time, tried setting different timezones, with reboots inbetween, same error
Internet options - SSL3/TLS1 and server certificate revocation, tried these in various combinations with reboots in between, no luck
Winsock reset and dns flush - Again I have tried this using various combinations of rebooting and not rebooting, running at elevated admin lvl and placing the whole lot of commands in a script to then execute itunes but still the same error occurs.
Running itunes as admin and safe mode - Neither of these two options helped at all
Running without AV software or windows firewall switched off - Yep have tried this as well, but no luck
Microsoft Hotfix for Crypt revocation -  2615174, no joy either
Revert to earlier version of Apple installer - ApplicationSupport 1.5.2  - tried a couple of earlier versions, same error
Removed itunes preferences - Had covered this during previous install processes but thought it might be worthwhile trying post install, no luck same error.
Winsock conflict - Yes checked the autoruns to see what else was there, only other entry was an entry for microsoft entry for msmail.
The environemt is a windows 7 machine with the latest updates, the itunes store did work previously but stopped in the last week of may (as I'm told by the owner of the laptop, yes people this is an inlaws machine). When I first looked at the notebook I checked that no new programs had been added after the date itunes store stopped working. The rest of itunes is behaving ok, that is if you accept that itunes is a good piece of software :-) with the exception of the diagnostic tool freezing when it runs (ironic huh?)
The owner did do the right thing before calling on me and spent several hours on the phone with Apple support to no avail and gave up in frustration, which apparently pleased the Apple tech.
I'm sure I've tried a few more things(like diferent internet connections to rule out any isp based issues(they do have another desktop in the house which runs itunes store ok)) but none come to mind as you can appreciate I've spent quite a few hours on this.
So calling on itunes gurus please come to the rescue, funny though the absence of apple techs replying to the already many threads on this on their own forums suggests that they don't have a solution perhaps "incapable of" or "not bothered", either way it's pretty poor.

Answer 1

I suspect the itunes error is related to a broken certificate chain.
"CertVerifyCertificateChainPolicy failed with error 0x80092013"
(log file under c:\users\[username]\appdata\roaming\apple computers\logs)
I took an image of the original machine and restored to a vm and pared down the system and used revo to clear out itunes 11, went back as far as itunes 9.2 looking to find some synergy with the v11 message.
Under v9 and v10 of itunes the store does not render correctly, the text displays but all images are omiited and just a placeholder is displayed. I've attached 3 images to illustrate, the first image is how the itunes store renders, I then copied the link from the itunes store and entered that into firefox (2nd image) and then lastly into safari. You'll see that itunes and safari are having the same problem rendering the page where as firefox is displaying correctly. (btw IE works the same as firefox)
Clicking on a link in the itunes store results in error msg 1202, this is consistent with v9 and v10.
Going back to safari I went to a secure banking site(www.netbank.com.au)to test a theory, basically the same behaviour is exhibited with the addition of a prompt from safari saying that the website certificate is invalid, the page loads just text with image placeholders but no images as though the css is failing validation. This also generates an error in the same fashion as itunes in the above log.
In the original post I had tried the Microsoft Hotfix for Crypt revocation -  2615174 as some people have tried this but uninstalling the hotfix and retrying did not work.
In addition I've tried various combinations of itunes with older versions of quicktime, even went to the trouble of extracting older versions of apple application support and running those against newer versions of itunes, all to no avail.
Some have suggested that this is a connectivity issue, so just to make sure I created a vm of my notebook and ran that against the non working version, so they had the same hardware, same network adapter, new ip stacks and of course the non working version continued to fail and my notebook vm worked ok.
Just to emphazie that the itunes store is connecting this is a screen shot of the store in column browser mode
(fyi - that's a really good book by SF, that one or the Hippopatamus)
I've also tried removing all the root certificates from the windows installation with the idea of retrieving them as required but this does not help, the certificates are retrieved but itunes/safari continue to have an issue.
As you might appreciate I've spent some time on this and would appreciate input from someone who can help, my lock and shammy have been seriously neglected .
