Changing the Grouping Size Of Windows in Windows Taskbar
If you are operating in Windows Vista and in Windows XP, the window of the various programs on the taskbar combines and group together if the number of buttons or windows increase which makes it difficult for the users as they can see one button along with one label that appears in the Taskbar.
For those users who want windows groping, together with similar windows but at a faster rate, for example after 3 or 4 similar windows for same application that are opened, without compressing them to the size of Taskbar’s button, windows provides TaskbarGroupSize which is a registry key that the Users can hack for changing the behavior of the Windows group as well as combining similar Windows.
TaskbarGroupSize is a registry value that is setting-based which defines the how many open windows of the same application can be opened on Taskbar before it is being grouped together in the Taskbar to one button.
In order to modify the Size value of Taskbar Group, you have to follow these steps:
At first Run Registry Editor (i.e. RegEdit)
Then navigate into one of the following registry key:
Command for present user who is logged on: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced
Command for every user accounts in PC: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced
Make a newly DWORD Value in right pane, and then enter TaskbarGroupSize as registry value.
Then double click in the TaskbarGroupSize, after that, change the value by which number of windows which will be opened in Taskbar as desired. For example, you want to group together 3 instances, the first to windows will not be grouped. Any three or more will be grouped into a single button on the taskbar.
To get your settings to work, restart your computer or you may re-login to see the necessary changes taking place.
