I experienced this week that the keys F1 - F12 isn't functioning any more in any application. I can't think of any big changes I did to the computer that would cause this.
There was some Windows Updates, but I think it was there before that and none of the updates said to be related to the keyboard.
I have rebooted several times while trying to work out what's causing it.
The keyboard is a wireless full size Microsoft keyboard for a desktop computer running Windows 7 64bit.
I'm wondering if there's an application that's claimed the keys for some functions. (All though - nothing appear to work when pressed.)
Any tools to diagnose keyboard issues like this? Inspect global shortcuts?
Something that would be quicker and easier than disabling all statup apps and enablind them one by one (that will just take a very long time.)
