Anyone running Device Guard with Symantec Endpoint Protection 14 on Windows 10 v1607?
I have a CI policy in audit mode applied and with SEP installed all the modern apps (Windows Store, Calc, Maps) open then crash right away. If I either remove the policy or SEP and reboot then the modern apps work fine. In event viewer under the Code Integrity section I get the error below which is related to the Application Monitoring in SEP, but the policy is in Audit mode so Device Guard shouldn't be blocking anything. Code Integrity determined that a process (\Device\HarddiskVolume4\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1611.3123.0_x64__8wekyb3d8bbwe\Calculator.exe) attempted to load \Device\HarddiskVolume4\Windows\System32\sysfer.dll that did not meet the Store signing level requirements. I've had a ticket open with Symantec for the last month or so, but they haven't been very helpful and claim they can't reproduce the error.
