Microsoft: Patch Tuesday update caused boot problems on some PCs

Microsoft send out word that a publishing error connected to the patches that were rolled out on Patch Tuesday caused boot problems on a select number of Windows 10 systems.

Users who use the regular Windows Update or Windows Update for Business service were not affected, the problem impacted customers who use Windows Server Update Services (WSUS) and System Center Configuration Manager (SCCM). Microsoft fixed the issue on October 10.

We have corrected the publishing issue as of the afternoon of October 10th and have validated the cumulative security updates. We recommend all customers take these cumulative security updates.

We have reports of the following symptoms impacting Windows Server Update Services (WSUS) and System Center Configuration Manager (SCCM) customers. Mitigation plans for the following user reported scenarios can be found below.

WSUS/SCCM Administrators that synced the October 10th update (KB4041676 or KB4041691) before 4pm PDT October 10 may still have these KBs cached.

WSUS/SCCM managed devices that downloaded the October 10 KB4041676 or KB4041691 update with publishing issues and have devices in a pending reboot state.

WSUS/SCCM managed devices that installed the October 10 KB4041676 or KB4041691 update and are unable to boot and/or may land on a recovery screen.
