This Win-11 21H2 OS build 22000.613 works differently on every system, even though MS has all the modern compatibility TPM, CPU etc. I have no issues with "Windows Media Player" as it works 100% but, I've had allot of problems with Bluetooth as my laptops the Acer Nitro 5 AN515-56 Intel Killer Wi-Fi/BT drivers only the latest drivers work for Wi-Fi and not BT as the BT driver refuses to work with the last Intel Win-11 driver and only works with the OEM Acer provided BT driver so, I'm running a different Wi-Fi driver to the BT driver. So as you can see there are allot of bugs and issues within Win-11 21H2 so we will just have to wait until MS fixes things?
