XNA - Windows Aero Effect is no more if you toggle full screen

Question

i am using togglefullscreen() function to ofc toggle between window mode & full screen for my application(game).

When i run the game in window mode, the title bar has the Windows Aero Effect of Win7 as it should be, but when i go full-screen and come back to window mode, then there is no more Aero Effect in window title bar, just a normal title bar

Similarly if i start the Game in full screen mode and then toghle to window mode, there is no more aero effect. Why is that happening & how to get back aero effect

Answer 1

Windows disables Aero because while you're inside a fullscreen app, the user usually doesn't see the title bar or task bar so it's just a waste of time to compute the 'good' graphics (transparency for example). If Aero doesn't restart after you close your program, then you can make a .bat file like so:

@ECHO off
net stop uxsms
net start uxsms

This will stop the service controlling aero, and then restart it (which always brings back the scheme if it should be there. (Obviously this is not in c#, but if you can do the same thing using the Process class, or by starting cmd.exe with some arguments. ("/C" will allow you to call commands from cmd.exe).
