We started testing rollout projects as a way for us to push out patches automatically through test group > pilot group > All PCs.
It seems to work out well with Windows 7 patching, as there is only 1 patch for 32-bit and 64-bit detection rule sets. The sampling size and criteria looks correct as well.
However, regards to Windows 10, there is a patch for each build of Windows 10, RTM, First Major Update, Anniversary Update, Creators Edition.
To me, it looks like the patch in rollout just checks for the OS version and adds them all into sample size but the patch can never meet the criteria target because the patch is is unable to install onto other versions from the sample.
Any help would be great. (we are still using 2016.3 SU1)
