Microsoft Releases Emergency Windows 11 Update to Fix Intel IPF Driver Performance Issues

Microsoft released out-of-band cumulative update KB5121767 for Windows 11 versions 22H2 and 21H2 to address performance, power-consumption, and system behavior issues caused by Intel Innovation Platform Framework (IPF) drivers—affecting a limited set of Intel IPF-equipped systems and some Dell devices. The update (which updates builds to 22621.889 and 22000.889) includes the IPF remediation, servicing stack update KB5120102, and Windows AI component updates; it is available via Windows Update, Microsoft Update Catalog, WSUS, and other deployment channels. Microsoft recommends that only affected systems install the update and that enterprise administrators validate it in controlled environments before wide deployment.
