Posted on March 5, 2026 by Júlio Barbas

A new Release Candidate (RC) version of the Patch Management Engine is being made available to N-central assets configured to use the RC channel. This release includes fixes focused on improving patch metadata accuracy, handling of new Microsoft update formats, and overall patch detection reliability.

Improvements Included

  • Improved Windows Server patch metadata accuracy: Resolves an issue where incorrect Windows Server version metadata could be reported from PME to the patch metadata service, potentially affecting patch applicability detection. (PMCM-11226)
  • Improved handling of Cumulative Update uninstall operations using DISM: Addresses scenarios where newer Microsoft Cumulative Update naming formats could prevent uninstall operations from correctly identifying applicable updates. (PMCM-11277)
  • Improved support for new Microsoft Out-of-Band (OOB) update titles: Ensures that newer OOB update naming formats can be correctly parsed and included in patch metadata processing. (PMCM-11295)
