The January update added the capacity to usage that registry worth to allow the defense protections for the vuln.

You are watching: A policy is in effect on your computer which prevents you from connecting to this print queue


This week, they began to obtrude (enable that automatically) there is no the need to develop the registry key.


At this point, the registry worth is only supplied to disable the protection feature.


Good discover for those who room having issues printing, as that vuln is not known to it is in exploited, when the ones that were spot this month are being proactively used.


Tradeoff is better.

Any idea yet why it division network print for some users? indigenous what I have the right to tell, if both the server and client have the January job (or later, together they space cumulative), then they are suppose come still be able to communicate through one another.

The difficulty with hiding the update is there space a lot of other security bugs in the that have actually been patched. Consisting of an MSHTML trouble that is being proactively exploited appropriate now.

First off, we do not forgive that form of attitude here in ~ Gentilkiwi came below to help, and your reaction is fully unwarranted. 

The civilization does not end if you uninstall this update. The security concern it band-aids, just would affect VERY specific setups. For many (99.5%) users, this security issue was never ever an actual difficulty in the an initial place.

Therefore yes, this is one extremely an important vulnerability. See this articles: Ransomware gang supplies PrintNightmare to breach windows serversVice society ransomware joins continuous PrintNightmare attacks 

Get her "Always to trust M$, never ever uninstall security updates!!!!" the end of here.

This declare is ironic as gentilkiwi has actually been placing Microsoft"s feet come the fire v this vulnerability and has been a substantial help in pressuring castle to provide adequate fixes.


So, yes, his explain is true. You must not uninstall the update if it deserve to be avoided as it is actively being used by threat actors.


Instead, girlfriend should try workarounds the leave the settle in place however resolve her printing issues. 


If those perform not work, climate you need to do what you have to do.


Finally, as gentilkiwi defined on Twitter, if you remove this update, you additionally remove protections for other proactively exploited vulnerabilities.
