Keyboard driver disappeared after latest updates

Hi Guys

I installed the updates last night and my keyboard stopped working. I then did a system restore and it worked again, so I tried running the updates again and the same thing happened. I have an old HP 9120 rf wireless keyboard which I like enough to want to try and keep. I can't find any hp drivers, but the driver that is installed now is just a standard ps/2 keyboard driver. After the updates there was no keyboard device listed.

I am sick of doing a system restore, so do I just find a new driver and install it after the updates with my mouse, or do I need to work out which update it is (or just buy a new keyboard)

I have Windows 7 64 bit.

thanks

Thanks
I fixed it, but it wasn't easy. I updated the HP driver then did the updates and it deleted the keyboard out of my device manager again. I installed the driver again and restarted but nothing happened. I restarted again and then it worked so who knows!!
I see there are more updates so if it removes my keyboard again I am going to be very annoyed!
