I have a question, I updated my laptop on windows 10 some time ago and when I switched my laptop on again, the background was black and the text money or green. Everything just works, I can't get rid of this strange color scheme. All buttons are also in such boxes ahh i want my old wallpaper back please. Anyone have any idea what that is or how I can get it away?
That sounds like "high contrast". Then
left ALT key + left SHIFT + PRESS
or
Start> Settings> Ease of use> High contrast
