Windows Update KB5077241 February 2026 Issues Nvidia GPU Bugs Task Manager Errors and ViVeTool Guide

Windows Update KB5077241, released in February 2026, is a 4.5GB feature update for the 24H2 and 25H2 versions. It poses significant performance risks for older hardware, particularly laptops and desktops without a Neural Processing Unit (NPU). Users with outdated Nvidia graphics cards, specifically the 900 Series (Maxwell) and 1000 Series (Pascal), report issues such as game stuttering, screen flickering, and system boot failures. The update also contains a flaw that inaccurately displays CPU usage in Task Manager, showing 0% utilization even under load. Many users face installation issues, encountering Error 0x800F0983, requiring them to delete update cache files and run repair tools. The update introduces features like a Taskbar Speed Test, Sysmon Security, improved Sleep/Wake functionality, and WebP wallpaper support, but many remain locked. Users can enable these features using ViVeTool with specific commands. Overall, the update is advised against for those with older Nvidia GPUs due to potential conflicts and performance issues.
