We have deployed Surface Pros to our field staff and are eagerly awaiting the upgrade to 8.1 to be released to consumers. We've been testing 8.1 RTM internally from TechNet and discovered that during the upgrade process we had to re-install all of the "old/Desktop" style applications, however, there has been some suggestion from Microsoft that the consumer release would be done through the Windows Store and wouldn't require re-installation of desktop applications. As opposed to installation via ISO files.
Does anyone here know whether or not the upgrade will require re-installation of desktop applications or could you point me in the right direction? Google is my friend, however, Microsoft doesn't seem to be saying much. Any help would be greatly appreciated.
