From PC World: Over the weekend, Microsoft released an unscheduled Windows 11 update, identified as KB5121767 for users on versions 24H2 and 25H2. The patch is intended to resolve an issue that’s occurring on a limited number of devices following the latest Windows updates.
Microsoft highlights this in the official release notes. The issue primarily affects certain Dell PCs and laptops running an Intel driver for the so-called Intel Innovation Platform Framework (Intel IPF)—the same machines that were blocked from receiving some Windows updates.
According to Microsoft, after installing the latest Windows updates, some devices may experience changes in system performance, increased power consumption, or unexpected system behavior. This is caused by a conflict with the Intel IPF drivers.
Those drivers are responsible for functions relating to power management, temperature control, and performance optimisation. If they don’t work correctly with Windows, problems with battery life, system performance, and/or system stability may arise.
