I have been attempting to build a Windows 10 Base Layer, which appears to capture and deploy fine. However, I am unable to successfully deploy a pre-packed Office Standard 2013 App Layer (built on Windows 8.1), where the post deploy results in failure for Office to initialise itself correctly. Even when using a Windows 10 Application Capture image to rebuild the App Layer, the same result is produced so initial comments are that Windows 10 will probably deploy if you put everything on the Base Layer! I'll try to deploy another layer at some point soon and was really hoping to have a Windows 10 image running on Fusion for VMworld next week
I'm running the Horizon FLEX deployed Mirage (so 5.4) to manage images, on vSphere 5.5u2.
