The first command creates the rule into memory, the second creates a rule variable, the third writes it to a new policy file called AllowNP.xml. Now we have a policy that blocks anything that isn’t signed as Microsoft, but we want to allow another publisher, in this example Notepad++, to do this we need to add a FilePath Rule to a new policy.xml and then we will build a new policy.xml file by merging both the AllowMicrosoft.xml and AllowNP.xml into one xml. Tip: Don’t try and build and extract the Base64 on the same machine you’re deploying to as you will get errors. The settings take effect straight away, no reboot needed, if you want to remove the policy then delete the above file and reboot. Now we’re ready to publish the profile to a device, once it’s landed on the end point, we can check it has applied by trying to run a non MS app such as Chrome or Notepad++, also check in: C:\Windows\System32\CodeIntegrity for a file called ‘ SIPolicy.p7b’ < this is our policy config. Then go back to the Policy Builder and change the config from ‘ADD’ to ‘DELETE’ and copy the SyncML into the ‘Remove Settings’ field in the UEM profile: Hit the ‘Copy’ button and paste into a new ‘Custom Settings’ payload:

In this article there is some overlap with the Microsoft commands as my intention is to give you the quickest and easiest route to deploying a MDAC policy just using the information here and not to have to go searching for the MS/PS commands needed.Īpp Locker came with Windows 7, WDAC came with Windows 10 1903, it’s much more powerful and will be fully supported by MS going forwards, read more here: So how do we get to this?: Overview:įor the purposes of this article, I’ll go through how to allow all Microsoft apps and Notepad++, anything else will give the above block message Microsoft Defender Application Control, (also known as MDAC) polices allow admins to control which applications can be run on a Windows 10 PC.
