There is a white highlight in the upper left corner of the screen (windows7 BUG)

        Windows7 is an excellent operating system, but for a big guy composed of massive code, it is reasonable to have some minor problems. For example, the previous solid background caused the Win7 login time to be extended by 30 seconds, and Automatic login causes the Win7 taskbar to be reset. Now, another small bug has been released. This time it is a joke with the monitor. Under certain conditions, there will be a white highlight in the upper left corner of the screen. But don't worry, your monitor has no problems, but Windows7 is a good thing.

so, under what circumstances it will produce the highlights? Microsoft's official knowledge base describes it:

1, if you are installing a Windows7HomeBasic version (ie family Standard Edition), when you change the desktop theme to "Windows7basic", and manually change the wallpaper of time;

2, if you are using Ultimate, professional or home Premium, when the user selects the "Aero theme (6)" any of a Windows7, buildings, figures, landscapes, architecture, scene And without selecting "Start Transparency Effect" in the window color, you will see a white highlight in the upper left corner of the desktop as shown below.

Currently, there is no patch for this bug, so if the user does not want to see the highlights, please avoid the two specified circumstances, until Microsoft officially fix the problem so far.
