Hello Fred,
Thank you for reaching out about your Windows 11 device not shutting down properly. I understand how frustrating it can be when your computer does not respond as expected, especially after repeated attempts. This issue often occurs due to power settings, background processes, or system configuration conflicts.
To address this start by disabling Fast Startup as it can sometimes interfere with the shutdown process. You can do this by opening Control Panel, selecting Power Options and under Shutdown settings unchecking “Turn on fast startup.” Next, restore your default power schemes by running the command powercfg -restoredefaultschemes in the Run dialog. It’s also helpful to run the Power Troubleshooter to detect and fix any power-related issues. If the problem persists performing a clean boot can help identify whether a third-party application or service is preventing shutdown. This starts Windows with minimal drivers and services making it easier to isolate the cause.
Could you let me know if you have already tried any of these steps or noticed any recent changes, such as updates or new software installations?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
