This also applies to win 8.1, posting here as this section has more traffic.
Whilst this may make things easier, it essentially removes a degree of control over which updates to install, now instead of each update been offered individually, there is just one big update which has them all included (security updates still be individual).
The first thing that comes to my mind is the win10 GWX update, I assume this will be in the big update, so a end user can either install no non security updates or all of them, not just "some" of them.
It is unknown at the moment if individual updates can be uninstalled after installing the big cumulative update.
I cannot help think with the timing of this, this is to get the stubborn people who have not upgraded, and started to hide the win10 updates to force their hand a bit.https://blogs.technet.microsoft.com/windowsitpro/2016/05/17/simplifying-updates-for-windows-7-and-8-1/
I do most of my updating via a 3rd party tool instead of windows update, hopefully individual hotfixes will sstill be packaged seperatly somewhere.
