Not Required as Compliant
In various in built reports for security update, Why do MS calculate its compliance considering updates 'Not required' as 'Compliant'?
Eg: Patch compliance report of a particular patch ->
All updates which compliance is mentioned is calculated with (Install + Not Required) / Total

I would say that it's because the update doesn't needs to be installed, which automatically makes the device compliant to that specific update.

Because you want to know for all of your clients what is your compliance for rate is. Thereby knowing what percent of your clients are a problem.
Assume you have 1000 Client, then assume that you have 10 client with Unknown State for KB1234567 and 5 clients with it installed and 985 that don't require that KB.
33.3% = Installed / (Installed + Unknown)
99% = (Installed + Not Required) / (Installed + Not Required + Unknown)
In both cases, you only have 10 problem clients but the second conveys that the problem is not that big of a deal as it only represent 1% of your total environment.

For Client point of view, where client is concerned with the patch compliance of a particular patch, they would more interested want to know the compliance on basis of total applicable updates. normally calculating compliance while including 'Not required'
will always give a better % in overall compliance.

True. In that case you should either run the report against a more representive collection, or create a custom report that looks at your specific requirements.

Ok, you will need to create a custom report which doesnt follow standard KPIs.
