Windows 10: Desktop background changing unexpectelly & black buttons

I set the Background picture to change every day. However the picture is changing in shorter intervals of time. Does anyone had this issue?
The symbol of Windows also turned black. I remember it was blue some time ago. Does Windows changed it?
