How to drag order of programs on the start bar in Windows 7?

Question

In Windows 7, seeing that you can drag and rearrange different applications, is there any way to rearrange separate instances of the same application?

I have an image to show you what I mean:

Answer 1

7 Taskbar Tweaker - This programs enables you to tweak your Windows 7 taskbar.

Features:

• Close or focus a window on middle click instead of running a new instance.
• Disable grouping of windows by file path or application id.
• Cycle through windows of a grouped button on left click instead of showing a thumbnails preview.
• Open with while dropping a file on a taskbar button instead of pinning.

Answer 2

By default, programs with the same application ID are grouped together. You can change this with a simple registry tweak.

Open regedit (Start -> type "regedit" in the search box and press Enter ). Expand the treeview to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer, modify the TaskbarGlomming value and set it to 0 to prevent the grouping.
