Windows Comulative updates

I have a question on Windows cumulative updates and I hope someone will clear my confusion.
We manually install the Windows updates every month, I have noticed the last two months there was another set of CU came in the fourth week of the month apart from normal Tuesday.
In this case, I had to schedule the reboot twice. I am thinking of skipping the one which comes after Tuesday's update and waits for next month hoping the missed update will be in the incoming CU,
For example, there was a CU with KB4550947 last month and I did not apply it. We have this month CU KB4556813
Will the KB4556813 include the last month KB4550947?
My other question,
Is there any way to find out whether the last month included in the new CU?

Cummulative Updates (CU) gets superseded all the time. There are A, B, C, and D week updates. Patch Tuesday is B Week. The other weeks tend to be preview or quality updates which eventually get rolled up into Patch Tuesday CUs. Unless these patches are marked as critical or security, you can skip them and focus on the true Patch Tuesday patches, plus any superseded ones that fix vulnerabilities etc.

Thank you all for your help. It is clear to me now.
KB4556813 includes KB4550947. How can I exclude that particular (KB*947) patch when I apply KB4556813?
We do not have SCCM/WSUS.

Hello There

You can't exclude an update from CU.

The solution might be installing updates one by one from the list, however, this would be time-consuming.

You don't need to worry about past month CUs, bcos they get superseded into the latest ones as I have mentioned before. Installed the most current CU which would be KB4556813. Furthermore, you will see that you will only be presented with one CU for Windows 10, and another possibly for .Net. 

The patch KB4550947 has something to do with cluster services as per the link below,
and the workaround is
Set the domain default "Minimum Password Length" policy to less than or equal to 14 characters."
Microsoft is working on a resolution and will provide an update in an upcoming release.
Our GP is set to use 12 charters.
I am not sure MS has fixed that issue with this month's CU.

We have Exchange 2016 DAG which is running on Windows 2012 R2. Will that be affected?

Thank you all
