Glad it worked for you.
There is a difference between an "Upgrade" and an "Update"
Is a Cumulative "Update" intended to be applied to Windows 10 Version 1703 and is not intended to "update" any previous versions.
The ISO for 1703 that you used to "upgrade" your previous version of Windows 10 to its' current state is just that...... an "Upgrade" that takes you from a previous version and "upgrades" your Operating System to the next version.
It's not really a vivid distinction but something I use by way of an explanation as to how to think about the differences and how you might distinguish one from the other.
Typically the words Upgrade and Update are used interchangeably, but....
I choose to make a distinction in my mind to separate the two processes as in
While I suppose you might say that you "Updated" from Windows XP to Vista or from Vista to Windows 7, what you really did was "Upgrade" the entire Operating System from something old to something new, so in my mind I choose to say that I "Upgraded" from Windows Vista to Windows 7, which I believe to be more accurate.
With Windows 10 no longer changing its' "core" name the distinction (if there actually is one) is blurred and Microsoft isn't helping by naming their versions as an "Update" at the end of the name, when in fact you are "Upgrading" the Operating System, just like when you "upgraded" from Vista to 7
Insisting on using the term "Update" associated with monthly (sometimes bi-monthly) "Cumulative Updates" and what seems to be their current strategy to bi-annually offer a new version of Windows 10 and also including the word "update" in the name of the process is not really helping to explain that the two are different and not really the same.
I'm sure that Microsoft would love for everyone to think that, an "Update" is an "Update" is an "Update" and everything is fine and there is nothing or no one behind the curtain, there not.....
As some are finding out, their systems may not be eligible for the soon to arrive Fall Creators "Update", because......
It's not. It's an "Upgrade" from an old Operating System, to a new Operating System and as a consequence, without special attention from manufacturers some stuff is just not gonna work.
