The Program window is larger than my Monitor window

So I've had this program for less than 12 hours and was playing with it when I noticed the bottom of the window went lower than my monitor. Using the Min/Max icon next the to x did not help at all. My computer is running windows 10 and, If it matters, I got he program with my Wacom Intuos tablet that I got today. How can I fix this? The program I'm Running is Painter Essentials 7

 I found another post that was 4 years old that had the same problem but I could not use the fix since I could not find the part of the Control panel that the post said would fix it.
