The following is the wrong answer. I misread the question. I thought the question was asking how to reset WindowBlinds. Since there is no option to delete this post I am putting this notice on it instead. Thank you to JanOscar for pointing out my mistake.
I know the answer. I figured it out myself by using the Windows search next to the Start Menu and searching for WindowBlinds.
What you have to do is uninstall WindowBlinds (using uninstall in your Windows settings), but then you have to delete the folder "WindowBlinds" in "C:\Users\Public\Documents\Stardock\"
When I tried this I actually deleted the "Stardock" folder in "C:\Users\Public\Documents\" because I didn't have any other StarDock programs.
Finally reinstall WindowBlinds. After I did this all my styles were reset back to the original settings. Yeah!
Also I highly recommend that right after you reinstall WindowBlinds that you backup your "WindowBlinds" folder that is in "C:\Users\Public\Documents\Stardock\"
What I did was I went into "C:\Users\Public\Documents\Stardock\" then made a copy of "WindowBlinds" right inside there. It named it "WindowBlinds - Copy" and I renamed it to "WindowBlinds - Backup Copy".
Hope this helps.
