Win10 system with a lot of themes, on the desktop can be updated frequently, so that the desktop feast for the eyes. A user found that the theme of the WIN10 system desktop suddenly turned black, this is not blot?
I initially thought it was a system update, but after a few updates, the problem remained and no solution was found on the web search. Today in an unintentional change theme, unexpectedly background color is no longer black, passed several tests, finally found the problem.
Win10 The default theme is 3, "Windows", "lines and Colors," "Flowers." If you switch to a line and color or a flower theme, the background color is definitely not black, and if you switch to a Windows theme or a downloaded theme, sometimes the background color is black.
To solve this problem, switch to the line and color or the flowers theme, and then switch to the theme that you like automatically, so that the background color is black. Once it appears again, you can repeat the operation.
What is the reason for black Win10 theme background? Nothing, it's a bug. It is believed that Microsoft will deal with this flaw in the Win10 of the test phase and give a solution.
