Microsoft has shipped out-of-band emergency updates to fix a bug that caused some Dell PCs to slow down or shut off after installing the July 2026 Windows 11 security updates.

The issue affects a limited set of Dell systems running Windows 11 25H2 and 24H2 after installing KB5101650. Microsoft said the underlying cause was introduced earlier, in the June 2026 KB5095093 preview cumulative update, which created a conflict between the new Windows USB-C Connection Manager interface and the Intel Innovation Platform Framework (IPF) Processor Participant driver.

On affected machines, Windows shows a yellow exclamation mark in Device Manager next to the Processor Participant driver.

“After installing the June 23, 2026, Windows preview update (KB5095093), a limited number of Dell devices might display a yellow exclamation point in Device Manager next to the Intel Innovation Platform Framework Processor Participant driver. These devices can potentially experience unexpected shutdowns, poor performance, increased heat, and battery drain.”

Microsoft

Microsoft had already blocked the affected systems from receiving the update while it worked on a fix. It has now released:

  • KB5121767 for Windows 11 25H2 and 24H2
  • KB5121768 for Windows 11 Enterprise LTSC 2024

According to Microsoft, the updates address changes in performance, power consumption, and system behavior tied to the Intel IPF driver issue. Dell devices that were temporarily blocked from receiving KB5101650 can now install the emergency patch.

Microsoft said the OOB update is only recommended for affected devices. Systems managed through Windows Autopatch with hotpatch updates enabled will get it automatically, while IT admins using Microsoft Intune can speed deployment with Microsoft’s published guidance. Users who have not yet installed the July 2026 security update will also need to restart their devices.
