I just tried to perform all of the most recent updates and that unfortunately did not work for me.
It is just not right that we have to then go into the registry and attempt to perform an edit to fix this issue.
This is just unacceptable!
The print nightmare debacle continues!
M$ - please get on this and offer a correct fix!
I reluctantly applied to the registry via an edit [after backing-up the registry] using regedit.
It worked; however, that really should not have to be the solution; and for some it may still not work.
Here's an article that may help others:
