I've already 3 different servers (Win2016-Win2022-Win11) that have LPD Service stopping/crashing after applying July Updates with CVE-2024-38027 

Anybody else with same problem? Removing Updates solved the problem but it's not the ideal solution.

    We are facing the same issues on our Printserver with Windows Server 2022. The Print Management Queue with the third party solution Canon Uniflow is not working anymore due to the LPD Service crashes, which coming with the newest windows Update KB 5040437.

    My workaround for that is at the moment the following:

    One revised the LPD service as a workaround and under Restore set all 3 parameters Service error to "Restart service" and Restart service after "1" minute.

    With this workaround the service is also crashing, but the one minute restart delay have no huge impact in our environment.

    Waiting for a fix...

    You Can definitely fix this with replacing the lpdsrv.dll in C:/Windows/System32 with an older version prior to this update. this is a rather "Quick and Dirty Fix" but does it for now.

    I have already been told "They are working on a MSI package that can disable the changes that were made. It may be ready later today for testing if I want to try it."

    This would be so we can leave the Cumulative update in place it seems for KB5040434.

    Sounds like a reversal to only the LPD service for CVE-2024-38027 - msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2024-38027
