The root cause is that Windows keeps separate power settings for every power plan (Balanced, High, Ultimate, OEM-specific plans), but the modern Settings app only updates the currently active plan, so other plans can silently override button behavior via GPU driver updates, OEM tuning software, or scripted powercfg commands. The fix rolls out gradually via Controlled Feature Rollout, so having the KB installed doesn't guarantee the fix is active yet. Users can check their build version (26100.9168 or 26200.9168 minimum) and verify behavior manually via Control Panel's power options or terminal commands like powercfg /list, /query, and /requests. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why does my desktop PC keep the fans running and screen off when I try to shut it down, forcing a hard reset? This happens because Windows maintains a separate full copy of power settings for every power plan on the system (Balanced, High, Ultimate, OEM-specific plans), but the modern Settings app only updates the currently active plan. GPU driver updates, OEM tools like MSI Center or Armoury Crate, or scripts using powercfg /setactive can silently switch the active plan, leaving your intended power button behavior unset on the new plan. _Track fixes for frustrating Windows power bugs like this one on daily.dev before they hit your machine._ ### What Windows 11 build number includes the fix for the power button shutdown bug from KB5121003? The fix requires build 26100.9168 or 26200.9168 at minimum, checkable via the winver command, but Microsoft is rolling it out gradually through a Controlled Feature Rollout mechanism. Having KB5121003 installed only means the device has the underlying method for the fix, not that the fix is active, so actual power button behavior must still be tested manually. _Developers tracking staged Windows rollouts can follow build-specific fixes like this on daily.dev._ ### How do I check which power plan is currently active on my Windows PC and what settings it contains? Open a terminal and run powercfg /list to see every installed power plan with an asterisk marking the active one, then use powercfg /query to view every value in that active scheme. Use powercfg /requests to identify which process is preventing sleep, and powercfg /setacvalueindex plus /setdcvalueindex to manually set button behavior before an official fix arrives. _daily.dev helps engineers troubleshooting OS-level configuration quirks stay ahead of similar fixes._ ## Similar posts on daily.dev - [Windows 11 won't let me shut down without an update, and I finally found a way around it](https://daily.dev/posts/windows-11-won-t-let-me-shut-down-without-an-update-and-i-finally-found-a-way-around-it-9s9bustap) · XDA Developers · 0 upvotes · 0 comments - [Patch Tuesday update makes Windows PCs refuse to shut down](https://daily.dev/posts/patch-tuesday-update-makes-windows-pcs-refuse-to-shut-down-9lzeby7fw) · The Register · 0 upvotes · 0 comments - [Windows hasn't properly shut down when you click shut down since 2012, and it explains a decade of weird bugs](https://daily.dev/posts/windows-hasn-t-properly-shut-down-when-you-click-shut-down-since-2012-and-it-explains-a-decade-of-w-2mawkwige) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#windows](https://daily.dev/tags/windows) [View this post on daily.dev](https://daily.dev/posts/i-stopped-force-shutting-down-my-pc-after-windows-11-s-august-update-fixed-this-one-thing-qjmlgb0gz) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I stopped force-shutting down my PC after Windows 11's August update fixed this one thing","url":"https://daily.dev/posts/i-stopped-force-shutting-down-my-pc-after-windows-11-s-august-update-fixed-this-one-thing-qjmlgb0gz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-stopped-force-shutting-down-my-pc-after-windows-11-s-august-update-fixed-this-one-thing-qjmlgb0gz"},"datePublished":"2026-08-25T00:01:03.745Z","dateModified":"2026-08-25T00:01:33.294Z","description":"Windows 11's August 2026 update (KB5121003) addresses a long-standing power button bug where PCs would fail to shut down properly, leaving fans spinning while...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/699140e37951f1f7f22c8a1543cedb3e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/699140e37951f1f7f22c8a1543cedb3e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/i-stopped-force-shutting-down-my-pc-after-windows-11-s-august-update-fixed-this-one-thing-qjmlgb0gz","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"windows","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"I stopped force-shutting down my PC after Windows 11's August update fixed this one thing"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/i-stopped-force-shutting-down-my-pc-after-windows-11-s-august-update-fixed-this-one-thing-qjmlgb0gz#faq","mainEntity":[{"@type":"Question","name":"Why does my desktop PC keep the fans running and screen off when I try to shut it down, forcing a hard reset?","acceptedAnswer":{"@type":"Answer","text":"This happens because Windows maintains a separate full copy of power settings for every power plan on the system (Balanced, High, Ultimate, OEM-specific plans), but the modern Settings app only updates the currently active plan.
