I am getting an AppHangXProcB1 error as I see in my Security And Maintenance Control Panel (sent here by my Event Viewer Log)


This is caused when trying to open ANY Powerpoint (.pptx) file in Windows Explorer, so far this is happening ONLY with .pptx files.


This is a brand new HP (bought yesterday) with Win 10 installed and running a fresh install of Office 365 - Powerpoint 2016


I ran the Office repair tool and reinstalled Office and still getting this error



The program POWERPNT.EXE version 16.0.9001.2138 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

Figured it out, seems that turning off Windows Firewall eliminates this issue, STUPID, since Office is a Windows programs
