I have installed the free upgrade to Windows 10 (64 bit) on my desktop PC. Other than having to download a few additional W10 drivers, everything seemed to work OK, until I installed the Mouse and Keyboard Center. My keyboard is a Microsoft Digital Media Pro keyboard connected via PS/2. Although the log shows the conversion successful, I have lost all of the function and hot keys. It operates as a basic typing keyboard, but that's about all. As it is not a USB device, the keyboard is not recognised. I don't really want to change my keyboard as I find the additional keys extremely useful. I have a PS/2 to USB adaptor, but I guess that isn't sufficient. I used the Intellitype/Intellipoint drivers with Windows 7 (64 bit) and had all keys functioning. I did try to re-install the W7 drivers, but failed. Any ideas on what to do? Thanks.
