Look for Caps lock, tap it once and see if your font returns to normal. I think he made it into all capital letters.

Look on the bottom right-hand of Internet Explorer. Is there a percentage listed? Anything higher than 100% will make the screen appear "bigger."

If you're using another browser that doesn't have that option, try pressing:
1. Alt
2. V
3. Z
And then try zooming out.

Can also try control+ and control-

Also check the control key is not stuck half way up or down.
