I am unsure where to report bugs so I'm mentioning one here. If there is a more appropriate forum then feel free to point me that direction.
EMET 5.5 beta on Windows 10 64 bit will fail to load on reboot after an install if group policy editor has been used to aggressively remove "features" from Windows. One notable problem is disabling Cortana in group policy editor. EMET on my box
really doesn't like that. This is unfortunate as I don't expect Cortana will ever be enabled on any of the boxes I oversee.
