As before, the update comes with minimal documentation and explanation. And, again, akin to previous instances, the updated code comes with a completely useful set of notes:
Jokes aside, the new update contains all prior cumulative updates, so
if you missed round one, or two, this should get you up to speed. On
that point we have to take a pause. Here’s Microsoft’s official words on
the update:
Windows 10 updates are cumulative. Therefore, this package contains all previously released fixes. If you have previous updates installed, only the new fixes that are contained in this package will be downloaded and installed to your computer.
Therefore, Microsoft will continue to release cumulative updates.
And, in that vein, I presume that the firm will shift the packages as it
updates the code it initially distributes via upgrades, and OEM
partners; it won’t need to send out July 2015 updates forever, since,
presumably, that code will eventually become standard fare. For now, you
get regular doses of new, and old.
And for fair play, these update packages are more background fixes
than new features. So that Microsoft isn’t saying much should fail
to surprise.
