Windows users will be able to automatically apply the security updates released today and designed to fix an intermittent print spooler service issue that may cause print jobs to fail via Windows Update, Windows Server Update Services (WSUS), or manually from the Microsoft Update Catalog. The printing issue was triggered by the Security Updates or IE Cumulative updates on September 23 to patch the CVE-2019-1367 security vulnerability.
