Change the Taskbar Group Size

By default taskbar grouping will happen when you have three or more of the same program windows open. 

There is a  registry key to change the settings so that, if you prefer, Windows XP will wait till you open even 

more of the same program windows before they start to group.



    * Open your registry and find or create the key below. 



[HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/Advanced]

"TaskbarGroupSize"=dword:00000003 




It's currently set at 3. Change this to whatever number you wish explorer to group at. i.e. change it to dword:00000008 

if you wanted explorer to group on 8, or dword:00000005 if you want explorer to group on 5.



Exit your registry; you may need to restart or log out of Windows for the change to take effect.
