Here are the details of my problem:

Setup Windows 8 Pro (64-bit) - create a new account called "Admin" with administrator rights.

Setup everything in that account (icons, Start Screen tiles, various Explorer view settings, etc).

Put an answer file in the sysprep folder which has the copyprofile set to True.

Run sysprep with generalize, oobe, shutdown and unattend with the answer file.

When sysprep is done - the system shuts down.

Fire it back up with Windows PE disk to access the hard drive.

Delete the pagefile.sys and swapfile.sys.

Copy the appsfolderlayout.bin file from the Admin profile to the Default profile.

Image the system.

Here's where it gets weird.  Fire the system back up (or on any system where the image is laid down).  Log in with the local "Admin" account that was the basis of the copyprofile.  IE10 (desktop) works fine.  I can log into various websites (SharePoint Online, Pandora, etc.).  Create a new user.  The profile copies over just fine - all the icons, settings, Start Screen tile layout, etc.  However, IE10 starts having problems with certain websites.  Pandora won't load.  SharePoint Online is missing the top bar (that says "Outlook, People, Calendar, Newsfeed, SkyDrive", etc).  I can't install website certificates - they just fail to load.

Metro IE works fine - Pandora loads, SharePoint online works - I still can't install certificates, but I think that's a limitation of Metro IE.

I've tried everything I can think of - Reset IE10 settings, copy the Admin IE registry keys over to the new user, allow the new user rights to the Admin profile.  Nothing gets the desktop IE10 working properly for those sites.

If I redo my base system and take out the "copyprofile" from the answer file - the problem goes away.  New users have no issues in IE10.  It's something that's happening when the profile is copied.

Any ideas?

Hi,

I suggest you not create an Admin profile to customize, use the built-in Administrator account directly for a test.

I'm glad you brought that up.  I just completed a new test, using the Microsoft instructions on the Administrator account.

I enabled the Administrator account, signed in and made all my configs on that (including the registry change to allow default apps to install on the administrator account).

Put the system in audit mode for sysprep to get the appfolderlayout.bin file.  Then did the full sysprep.  Same problem happened.  The built in Administrator account was disabled by sysprep, but the other local account that was there would work fine in IE10.  When I created a new user, which copied over the modified Administrator profile, various websites stopped working in IE10.

I'm not sure how I'm going to proceed with testing...  I may try stripping down the XML answer file to just have "copyprofile" only and not any of my other settings (time zone, default language, organization name, etc.).
