Go ahead and download the driver again.
Go ahead and run it, it will ask you if you want to repair the OSD Driver or remove it.

Remove it, then restart your computer.

If you want to have the OSD back to the defaults, go ahead and install it again.

thanks, i'll try it out

Hi Jose

Hi Jose:

Finally I find the solution:

[HKEY_LOCAL_MACHINE\SOFTWARE\Widcomm\BTConfig\General]

"KeyIndication"=dword:00000001

change the value to 0 and restart system
