Grammar and spelling corrections for GC text.

So I'm sure all of you computer whizzes are well aware that people who have HP computers don't have the ability to see if they're spelling things wrong in the box that I'm typing in right now. I got my HP today and had a dell before this. The HP doesn't give me the red or green line underneath my text if it's incorrect. I'm sure there is a way to fix this.

Can someone help me out?
Thanks.
