For each WDEG ASR rule, it would be useful to list which version of Windows 10, Windows Server, and SCCM CB the rule was introduced.
As an example for the "Block persistence through WMI event subscription" rule there could be something like below.
This rule was introduced in:
- Windows 10: 1903
- Windows Server: 1903, LTSC vNext
- SCCM CB: 1902
Could also flatten it too:
This rule was introduced in Windows 10 1903, Windows Server 1903, Windows Server LTSC vNext, SCCM CB 1902
Below are my notes for each rule, but I'm not sure if it is totally accurate. I wasn't sure about some of the versions (denoted with ???):
My sources for SCCM versions are:
My sources for Windows Server and Windows Server LTSC are:

@illfated I can double check these tomorrow in my SCCM 1902 instance to try and answer some of these questions below. Here are my comments:
Block process creations originating from PSExec and WMI commands
SCCM name: Not applicable.
Is that correct? Makes sense if that's true because it isn't compatible with SCCM. Might want to remove "SCCM CB 1802" then.
Block Office communication application from creating child processes
SCCM name: Not yet available.
Is that correct? Seems like it should be there. Might want to remove "SCCM CB 1810" then.
Block Adobe Reader from creating child processes
SCCM name: Not applicable
Is that correct? Seems like it should be there. Might want to remove "SCCM CB 1810" then.
Block persistence through WMI event subscription
SCCM name: Not yet available
This might actually be true since it is so new. This one is missing "This rule was introduced in:" phrasing. It should be in Windows 10 1903.
Thank you for those comments and your suggestions for what else needs to be remediated.
I am confident that this can be resolved too, as soon as any of the other contributors will add it to their work list.
I would have taken the time myself, but I have got too many distractions going on in my life at the moment.
@illfated So it turns out that those 4 rules are not in SCCM CB 1902. I'd remove all mentions of SCCM CB for those rules in their "introduced in" lines. Outside of that, I wonder why the Adobe Reader one is listed as "Not applicable" instead of "Not yet available". It makes sense that "Block process creations originating from PSExec and WMI commands" is Not Applicable because it will break SCCM. I don't think that would be true for the Adobe Reader rule. That's the only other thing that might need to be changed other than what I mentioned already.
