Your keyboard seems to be broken too. Your capital letters aren't showing.
You haven't given much detail to be able to help.
Try accessing that function in different ways- but you haven't said how
you've tried in the first place.
Try through the control panel. Try through the Run dialogue-
%SystemRoot%\System32\wscui.cpl
What exactly is your error message? How are you signed on- user, admin?
And any other info that you may have that would allow people to give the
help you ask for.
