In one of my posts I have explain how you can create an apply assignment filters. Is a very powerful feature to refine the assignment of group. For example, you can assign a config profile to all devices and apply a filter to apply the config profile only on Windows 11 devices within the group. To make it easier for you to start with filters I wrote a script which creates a default set of filters.
With the introduction of Assignments filter, the value of Applicability rules has diminished. With Applicability rules you could define on which OS versions a Configuration Profile should work. Unfortunately, the ability to configure or delete applicability rules for some configuration profile types from the console has also been removed. It is to be expected that this can happen piece by piece also for further types. In this blog I want to show you how you can easily remove all applicability rules to switch to filters as soon as possible.
