When I switched to Windows 7 from Windows XP, I was happy to find I could pin programs to the Taskbar.  But then became unhappy once I realized I couldn't move & reorder multiple instances of progams — like 2 Excel spreadsheets or 3 Word documents — independently; all Excel files and Word documents were grouped together, and I couldn't move the individual files where I needed them to be on the taskbar.

And then I found a free app to fix it — the 7+ Taskbar Tweaker — yay!  It's a free utility that's easy to install and customize. (Note: If you use Windows XP, you can install the free Taskbar Shuffle utility instead; I wrote about it in this April 2009 Ides post.)

Here's what my Taskbar looked like before installing 7+ Taskbar Tweaker:

Here's how to install +7 Taskbar Tweaker on your computer:

1. Go to http://rammichael.com/7-taskbar-tweaker or click on this link http://rammichael.com/downloads/7tt_setup.exe to download the file.
    
2. Click "Save File" on the window that opens up.
   
    
3. Locate the downloaded file (hopefully, you saved it to your Desktop so it's easy to find) and double-click the icon.
   
    
4. Click the "Run" button on the security warning window. (P.S. Pete has given his okey-dokey for this software.)
   
    
5. Once it's installed, you see the Taskbar Tweaker preferences window open up.  Here's a screenshot of the choices I made, but you may want to see what works best for you:
   
    
6. Click the red X in the upper lefthand corner of the preferences window, and you're ready to drag & drop apps around on your taskbar to where you want them!
