Windows 10 OS is a different story you will need to manually download and install the driver as for xp i don't think it was made for xp you may need to look around so far i have not seen anything
The 788 is compatible with Win xp through 10. The only issue you will have is the Simulated surround sound software. That will only work with win 8 and above.
Unfortunately it doesn't work on the PS4 with the 7.1 Surround since the surround is a software update that only works on PC. The good news that this is compatible with the PS4.
Hello- The GameCom 788 is the newer version. They will be the same as far as features and functionality goes but with some cosmetic differences in the color.
