A recent Windows 11 update resolves a longstanding problem where PCs appeared to ignore shutdown commands due to misaligned power plans, but some users report new issues affecting gaming performance.
Microsoft has quietly fixed a long-running Windows 11 irritation that made some PCs appear to ignore shutdown commands. The problem was not usually a failing power supply or broken button. In many cases, Windows was following a different set of stored power settings from the one users had just changed, which meant a machine could look as if it had frozen when it was actually using the wrong power plan.
The underlying issue comes from Windows’ older power-management system, which still sits behind the modern Settings app. Each power plan keeps its own copy of button actions, display timers, sleep rules and related controls. Changing one plan does not update the others, and some systems switch plans automatically after driver updates or through manufacturer utilities such as performance modes in tools from MSI, Asus and Lenovo. That is how a simple press of the power button could become a ten-second hold, followed by a forced shutdown and the usual risk of lost data or a messy restart.
According to XDA Developers, the August Windows 11 update introduces a fix through Microsoft’s Controlled Feature Rollout system, rather than turning it on for every machine at once. That means installing KB5121003 does not guarantee the behaviour change is active immediately. The report says users on builds 26100.9168 and 26200.9168 should expect the correction to arrive gradually, and that they should still verify their own settings manually in Control Panel or with the powercfg command-line tool.
That advice matters because the symptoms can look like hardware failure. A desktop may leave fans spinning after the display and peripherals have turned off, while laptops may fail to wake cleanly after lid close or power-source changes. Microsoft’s fix should reduce those false alarms, but users with custom power plans should still check that each active scheme matches their intended button and lid actions. Windows Central has also reported that the same August 2026 Patch Tuesday release, KB5121003, has caused separate problems for some gamers, including crashes and unresponsiveness in titles such as ARC Raiders, MARVEL Tōkon: Fighting Souls and The Finals, showing that the month’s update has been a mixed bag for Windows 11 users.
