So I have had windows 10 on the computer for a while now.(ca. 1.5 years) About a week ago all the colors and backgrounds was messed up on only my dads user. Then now it happend on my user too. I do not know what is causing the problem or how to fix it, so thats why I ask here. How do I fix this? I will leave a screenshot or two so you can see. (Sorry for bad English.) Thanks.
