It looks like Microsoft won't release a fix for this problem on the main release channel where all the updates are coming from. The fix is known for some time, but it is not available on the release channel for some reason. I guess that fixing the problem makes Windows a bit less secure, than without that fix. At least that's my guess...
If you have a problem with your printer you can try to solve it by installing a patch from Microsoft manually.
First read about the patch here:
https://support.microsoft.com/en-us/help/4567523/windows-10-update-kb4567523
And then you can download the patch and install it manually (choose the correct version of your Windows):

The above solution has worked for my Brother printer.
I have downloaded the correct version msu, but when I go to install it, I get the message 'The update is not applicable to your computer'
I have tried with all the versions to be on the safe side but it keeps saying the same thing.
P.S. I removed KB4560960 but that did NOT solve the problem for my Brother printer.
