If you often enable multiple applications when using your computer, you should cherish the space on the taskbar. However, whether you browse the Web page or use office software, you may need to open multiple Windows, which will fill the Windows XP taskbar.
Now, the group taskbar function of Windows XP can put the same or similar programs in a group, so that you can select multiple program Windows by clicking one window icon. By default, Windows XP ranks the first program to open first. However, by adjusting the registry project, we can optimize this combination.
Run the Registry Editor, expand the [hkey_current_usersoftwaremicrosoftwindowscurrentversionpoliceradvanced] branch, click the "Edit> New> DWORD Value" command on the menu bar, and name the DWORD Value "TaskbarGroupSize ".
Double-click to change the key value of the DWORD:
0 -- Windows XP puts the earliest opened program at the front.
1 -- Windows XP puts the largest program in front.
2 -- Windows XP combines two or more Windows with the same program.
3 -- Windows XP combines three or more Windows with the same program.
Close the Registry Editor and restart the computer as needed. The taskbar will be rearranged and grouped as required.
