Why my desktop wallpaper is not showed? I cant change it! I deleted some programms meybe thats why? My background is dark blue color and I cant change it
I think I know what you meaning, this is a bug, this is happen when you delete the wallpaper picture file and change resolution right(?).... You should define the wallpaper as a desktop background again.
Probably you deleted the picture set as your wallpaper and when you try setting it back, you can't as it isn't there anymore. Try using another wallpaper.
haven't experienced that yet... maybe it's a bug on your OS. Maybe next time, better check the files you are deleting whether they are important or not...
