Multitouch gestures and function keys aren't working

Everything was fine, multitouch gestures and function keys were fine, but I had to revert windows\system32\config\system file due to a power failure.
I reverted it and had to reinstall my drivers. I had to get Boot Camp drivers from a flash drive (got a stuck CD), I installed them, but touchpad and keyboard weren't working. I rolled back to Windows drivers and the problem appeared. How do I re-enable multitouch gestures and function keys? Is it because KbdMgr.exe thinks those aren't original Apple touchpads and keyboard?
