Can't say much about 9369 as I never had it before. In 30 minutes now though.. I do can say that 9378 (No typo.. ) is buggy. Your decision on that. But lets not get further off-topic.. someone should go look into the TwinUI.dll and look for the CanSupressStartScreen code..
Na, that one was fake. The number after PARTNER_OUTxx is unique. And 9364 was 13 so there can't be another 13..
Copy the contents of the Windows 8 RTM folder C:\Windows\WinStore over the one from Windows "Blue" and replace everything. (please make a backup of the folder first). You will need to takeown of the files from that folder. I haven't tested it on 9369 because I hate x64 builds (please no haters, I prefer x86, I have 4GB DDR3 anyway...). This method worked for me on 9364! If you have any more questions please PM me.
i tired it, copyed from windows 8 pro rtm x64 and store just stuck at loading. so i can just sideload apps.
to the question from the video about company apps. It is a setting from Windows Phone 8. Interesting to see it here. It's for setting up "policies, certificates and apps that help you connect to your business". Also, "your company would be able to disable your SD, encrypt your internal storage and remotely delete all you content and settings" (ouch). cheers
