Prompted by a warning about installing a printer driver, or the driver may fail to install without notification (4292206)

If network printers are in used in profiles, one of the following issues may be experienced:

A warning prompt may appear about installing a printer driver, or the driver may fail to install without notification after Windows Update MS16-087 is applied. The symptoms here depend on the specific scenario.

Scenario 1
For non-package-aware v3 printer drivers, the following warning message, "Do you trust this printer?" may be displayed when users try to connect to point-and-print printers:

Scenario 2
Package-aware drivers must be signed with a trusted certificate. The verification process checks whether all the files that are included in the driver are hashed in the catalog. If that verification fails, the driver is deemed untrustworthy. In this situation, driver installation is blocked, and the following warning message is displayed "Connect to Printer - A policy is in effect on your computer which prevents you from Connecting to this print queue.":

Scenario 3
For non-interactive scenarios (for example, the printer is installed through an automated script), when the printer driver matches the criteria that's described in either Scenario 1 or Scenario 2, printer installation fails, and no warning message is displayed.
