Known issues in this update


Symptom Workaround

Applications and printer drivers that leverage the Windows Javascript engine (jscript.dll) for processing print jobs might experience one or more of the following symptoms:

  • Applications interacting with the V4 printer driver might close or error when printing. Issues might only be encountered when printing but might also be encountered at any time the app is running, depending on when the app interacts with the print driver.
  • The printer spooler service (spoolsv.exe) might close or error in jscript.dll with exception code 0xc0000005 causing the print jobs to stop processing. Only part of the print job might print and the rest might be canceled or error.

This issue was resolved in KB4517389.
