@udaraso thanks - unfortunately that doesn't help with my situation, where I use the same Bluetooth Keyboard and Mouse with two computers (switching from the USB receiver on the desktop to the Bluetooth on the Laptop). It worked fine with Windows 10 but not Windows 11. I have ended up having to use a separate mouse for the laptop and having to use the laptop's built-in keyboard, which is not ideal for my setup (it is docked on a stand). Should be possible to just update the driver to stop this happening (or I may try to roll back the Intel Wireless Bluetooth driver to a version that worked such as v21.110.0.3).
