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

Windows 7 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 the use of automatic login caused 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 doesn't have a problem, but Windows 7 does a good job.

So, under what circumstances will this bright spot be produced? Microsoft's official knowledge base describes it:

1, if you are installing Windows 7 Home Basic version (ie family Standard Edition), when you change the desktop theme to "Windows 7 basic" And when manually changing the wallpaper;

2. If you are using the Ultimate, Professional or Home Premium, when the user selects "Aero Theme (6)" Windows 7, Building, Any one of the characters, landscapes, buildings, scenes, and do not select the "Start Transparency Effect" in the window color, you will see a white highlight in the upper left corner of the desktop as shown below.

At present, there is no patch for this bug, so if users don't want to see this highlight, please avoid the above two specified situations until Microsoft officially fixes the problem.
