Patch to Fix PrintNightmare Vulnerability

In June of 2021, after we installed a patch from MS, users couldn't connect to network printers without having admin right. Per Microsoft, the patch named KB5005625 released on Sept 21, 2021 which was superseded by KB5012647 would fix the issue for good. After we installed the patch KB5012647 this month, we still ran into the same issue where users had to use admin right to install printers. Do I need to do anything else after I install the patch in order to fix the issue for good?

Hi there,

The patch CVE-2021-34481 for the Windows Print Spooler Remote Code Execution Vulnerability was updated on 10 Aug 2021.

On September 2021 Patch Tuesday security updates, Microsoft released a new security update for CVE-2021-36958 that fixes the remaining PrintNightmare vulnerability.

Check if you have got all the latest updates that would have incorporated all these patches. For some workarounds, you can check the below thread where several workarounds were posted by several users.
