Minimize MSN Messenger to the system tray in Windows 7

Strange issue on MSN till that current version I'm writing here, V2009, Build 14.0.8064.206, when application minmized it remain in the taskbar,

Solution is easy until MS patch this,
1- Close MSN
2- Open the MSN exe folder
3- Change the Program Compatibility to Vista (any)
4- Run the MSN again , it will change some registry settings while loading then you find it isnide the System tray !
