In Windows 7, Microsoft adds a new feature to the Desktop window: smart arrangement. In fact, translation into "smart permutations" is not very accurate, because in Windows 7 desktop Windows, some applications will automatically maximize or occupy screens on both sides of the screen at the top or left and right sides. If you are not accustomed to this default behavior, you can completely block it.
Run the registry, navigate to HKEY_CURRENT_USER "Control Panel" Desktop, locate and double-click "Windowarrangementactive" in the right window, and then in the pop-up dialog box, change the system default value "1" to "0." ".
Although I share this method with you, I do not agree with you to modify the system default settings too much. Because of some of the default settings for Windows 7, there are a number of improvements relative to Windows XP that are more tailored to the actual needs of the user. And users now think that Windows 7 is a problem, just a matter of using habits.
