Some times Microsoft does good work on hardware. That is keyboards and mouse.
The problem is that they do it in their own way => Friendly for the user. Or as they think that is friendly 🙂
On the office keyboards the Function keys has been replaced by functions eg Help,Undo,Redo,New etc.
But i don’t want to press the F-lock every time i do an Alt-F4 to close the window.
If you want to invert the f-lock download and import the registry fix from the following site http://www.mvps.org/jtsang/flock.html
Finally….. Pressing Alt-F4 works 🙂
