I have a Samsung Series 7 Ultra laptop as mentioned in the title above, which came pre-loaded with Windows 8 about 6 months ago. Last week i updated the same to new Windows 8.1 preview to test out the new things, specially the Start Menu. Well i noticed few interesting stuffs with the new OS but simultaneously got some new problems as well. Installation went fine without any problems but dont know why my function keys stopped working. I am not able to use any key shortcut from the top row that includes Turning on/off bluetooth, wifi, touchpad, etc, hence things got worst.
Now can anyone please suggest me the best thing i can do? I mean there seems no way to revert back to earlier OS as well, neither i am able to make my function keys work with this OS. Stuck badly. Please help.
