Here is my last session and screenshot. After installation, no metro apps are available on the start screen for running, except metro IE and app store. However, even if I use a non built-in administrator account with UAC on to run them, they will be automatically closed right after I clicked and opened them. I'm pretty sure there must be some reg tweaks in WinToolkit that disabled the metro app platform or app container from being installed properly during windows installation, but I just don't know which tweaks. Can someone help me? Thanks. BTW, it was installed on a VHDX for native boot by using imageX /apply, without any unattend.xml. Update: Problem is resolved. Do not touch services, especially the task scheduler. 2012-07-11_06-10-07_2012-07-11_06-10-07.ini
