I'm attempting to manually install critical-only updates to a Win 8.1 box.
I found April 2017 windows8.1-kb4015550-x64_516ecbc130cb85fe3ae74f04c9f2cc791b669012, which i believe is critical updates only. Great.
https://support.microsoft.com/en-us/help/4015547/windows-8-1-windows-server-2012-r2-update-kb4015547
But, it's prerequisite is April 2014 KB2919355, which is over 700 MB.
I suspect that, at that size, it's not a critical-only update, but instead includes all updates up to that point (even non-critical stuff not required for the 2017 update). Correct?
If so, how can i identify the absolute minimum prerequisites needed for the April 2017 update? -thx
