#PatchTuesday 2026-10 Patching experience in my test lab (#homelab). Windows 11 - No issues on any test machines / VMs. A physical workstation had 1 minor issue. Windows 10 - ESU enabled physical system updated normally, but there was another update to the Recovery Environment (KB5131595). No updates for non-ESU test VMs. Windows Server 2016 - Normal, Servicing Stack Update (KB5126649). New Servicing Stack every month now, I guess. Windows Server 2019 - Normal, uneventful. Windows Server 2022 - Normal, uneventful. Windows Server 2025 - Normal, uneventful. Note: 1411 fixes, 3 zero-days, per bleepingcomputer. Giant set of fixes, but uneventful in my homelab. https://www.bleepingcomputer.com/news/microsoft/microsoft-october-2026-patch-tuesday-fixes-1-411-flaws-3-zero-days/ Note2: Within 24 hours, one of my physical Windows 11 systems randomly rebooted w/ a fatal hardware error reported by component: Processor Core (Machine Check Exception / Cache Heirarchy Error), might be nothing or random.
