Microsoft Releases New Windows 11 Security Update Fix For Dell Users - Forbes

What the report says

Forbes reported that Microsoft has issued an emergency out-of-band update for Windows 11 after its July Patch Tuesday release caused problems on some Dell computers. The fix applies to Windows 11 version 25H2 and 24H2 and is identified as KB5121767 for builds 26200.8894 and 26100.8894. Microsoft said the new update is intended only for Dell users whose machines were affected, and that others do not need to take action.

According to the Forbes article, Microsoft had taken the unusual step of blocking the July Patch Tuesday update, KB5101650, for certain Dell systems after it was linked to performance issues and, in some cases, shutdowns. The reported cause involved a conflict between the Windows USB-C Connection Manager interface and the Intel Innovation Platform Framework Processor Participant driver. Forbes said affected models included the Dell Pro Max 14 Premium MA14250, Dell Pro Max 16 Premium MA16250, Dell XPS 17 9720 and Dell XPS 17 9730, though the article did not present a complete device list.

The report framed the Dell fix as part of a wider pattern of Microsoft update complications. It cited past examples involving VPN disruptions, third-party backup services and an April 2026 optional update where extra restarts following a Secure Boot certificate change prompted user concern, even though Microsoft described that behavior as expected.

Forbes also noted a separate Microsoft-confirmed issue involving Windows Server Update Services that can cause Windows Update scan failures across multiple client and server platforms. Microsoft attributed that problem to accumulated publishing metadata and recommended cleanup steps for existing WSUS installations, while saying a service-side mitigation had been deployed for new installations and rebuilds.
