[1709, fcu] Apps are blocked

[Chuckster]

Since Friday the entire school has been experiencing this problem and I don't know what the root cause of the problem is.

 

When you launch something like Device Manager, Disk Management etc I am presented with this and I can't get around it at all:

I have searched high and low for a solution. I've disabled UAC to the bare minimum, both in the control panel and in a GPO, to no avail.

 

None of the GPOs had been edited or played around with for almost 6 months.

I've rebuilt a workstation and the problem persists, which leads me to believe that it can't be a Windows update, as many of the workstations were rebuilt last summer.

 

I am at my wits end with this... please help!

Is applocker blocking them from opening?

[Chuckster]

We are not using applocker, therefore the Application Identity Service (AppIDSvc) is permanently not running.

Anything in the event logs from Friday?
