Since installing Windows XP SP3 in my system, my Microsoft Bluetooth keyboard has stopped working. I have tried uninstalling and re-installing software for it but it doesn't work. There is nothing wrong with the keyboard as i have tested it out on another system running xp and it was working fine there. It seems as if there is something wrong with Windows XP SP3. Has anyone else faced the same issue???? Is there anything i can try out to get Microsoft Bluetooth keyboard working with XP SP3???
