Cannot Print to PDF or Distill PS in Windows 10 1709

I would have posted this as a comment in the Frame 2017 cannot print to PDF or PS or Printer as of April 6, 2018 thread if it was not locked.

I am running Windows 10 Version 1709 OS Build 16299.579.

Any attempt to create a PDF with “Convert CMYK Colors to RGB” selected, results in PostScript error: “Error: typecheck; OffendingCommand: findfont; Stack: /Font (Courier) /courier” Clearing the “Convert CMYK Colors to RGB” check box results in a PDF, but with unacceptable color shifts (described as “very washed out” by posters in the other thread).

I cannot install the fix released by Microsoft on July 24—KB4340917 (OS Build 17134.191—because my company restricts updates via WSUS. I tried downloading and installing the standalone package but got: “The update is not applicable to your computer.” Not surprising because I’m not on Windows 10 version 1803. Because I can’t install the update that fixes the problem, I’m hoping I can uninstall the update that introduced the problem.

My question: Does anyone know which Windows 10 version 1709 update might have introduced the problem? Thanks!
