Okay, the latest Windows update added something that I actually find useful. Now when you hit the numeral lock key an icon appears onscreen saying either "num lock on" or "num lock off." The caps lock key has always had a light that goes on when your caps-locked, but for some reason the num lock didn't. But now it's okay.
The thing is, I never want to have the numeral lock on. I prefer to use those ten buttons on the side for scrolling shortcuts and use the number keys at the top of the keyboard. This is apparently a weird preference, as I'm reminded whenever I work in an office.
