Microsoft has halted the deployment of its latest Patch Tuesday update for Windows 11 on select Dell PCs due to incompatibility with Intel's IPF driver, which caused issues such as unexpected shutdowns, overheating, and decreased system performance. Microsoft is working to resolve these complications and has released an emergency out-of-band update, KB5121767, for Windows 11 versions 24H2 and 25H2 to address the concerns.
