If there is no Bluetooth toggle in the Windows settings, try the following workarounds. This is a common workaround for most Bluetooth devices that suddenly stop working in Windows 11/10. You can also try removing and disconnecting the Bluetooth device, then re-discovering and pairing it again. If it’s on and still not able to detect your Bluetooth mouse, headset, or keyboard, check your device/peripheral to see if it’s properly switched on, has a working battery, and is not broken. If the Bluetooth option is visible and turned on, Windows should be able to discover other Bluetooth devices near your PC.
