I just found out that paint isn't completely useless!!! You can use it to make caps, unbelievable I know but you can!! Interested? I'm using it for YouTube videos but I'm sure it works for other videos too.
1. Hit the Print Screen button on your keyboard.
2. Open up a new Paint document and paste it there.
3. After that click on the little dashed box.
4. Cut out the portion you want.
5. Hit CTRL+X and the selected part should be white.
6. After that hit CTRL+A+Delete (the whole screen will be white.
7. Then hit CTRL+V and the part you wanted should be in the top left corner.
8. Resize the paint page and paste the picture...and you're done.
Example
It's a little blurry but I'll work on that. Anyways, enjoy your caps!!
