I have come up with a solution to your problem. I accidently clicked and turned on high contrast. When I clicked to turn it off, nothing changed. I went online to chat with an online Microsoft representative. A man remotely controlled my computer to fix the problem. I know what to do. Go to your start page, then click on desktop. Once you get to your desktop, RIGHT CLICK on the screen. A small box will open to the right of the pointer. Click on PERSONALIZE. Then click on the WINDOWS theme under the 3 default windows themes. You will click on the one with the flower on it. This will turn off you high contrast
