I recently installed the Windows 11 version 25h2 on my laptop, and my Bluetooth stopped working. In fact, the Bluetooth setting disappeared entirely. I tried everything I found online, but it didn't help. I was eventually able to get my Bluetooth to work again by reinstalling the current version of Windows. Below are the steps:
Steps to reinstall Windows
- In the Settings app
on your Windows device, select System > Recovery
- Under Fix problems using Windows Update, select Reinstall now

- In the Fix problems using Windows Update window, choose if you want to allow the PC to automatically restart 15 minutes after the installation completes

- Select OK when you’re ready to start the installation
- The reinstall will take you to the Windows Update page in Settings. It will start downloading a repair version of the last operating system update that was successfully installed on your PC. Once the download is complete, the repair version of the update installs
- Once the reinstall is complete, restart your PC if you didn’t choose to allow it to restart automatically
After restarting, I checked and confirmed that my Bluetooth settings are functioning properly. I also tested all my Bluetooth devices to ensure they are working properly. Please give a thumbs up to let me know if this information is helpful.
