MBP certain keys on keyboard stopped working in Win 7
I most often boot up the MBP to the Windows OS. It used to all work fine. About a week ago, the problems appeared.
The top row of keys on the keyboard are not operating correctly (in particular, the F1 thru F12 keys). And the keyboard-backlighting does not light up at all.
In order for it to register a "F1" keypress, I must press fn+F1 (function-key + F1 key). Same situation for F2 thru F12.
Their alternate functions* do not work at all, no matter what I try.
(*LCD brightness down, up; keyboard-backlight brightness down, up; media <<, >||, >>; audio mute, volume down/up).
When booted up with the Mac OS, everything operates correctly!
I have already checked the Boot Camp settings - no effect.
Could the Apple's keyboard drivers KeyAgent.sys & KeyMagic.sys not getting loaded or be corrupted? If so, where do I find original copies of them?
