This is a HowTo for using individual Windows 7 Start Buttons without patching the explorer.exe. The Idea came from
MaxFragg
. The HowTo is mine

.
First Step:
Download the Application
Start Killer
. A 64-bit-Version is also available at
Tordex - Free Downloads
. This will Remove the (original) Start Button from the Taskbar.
Second Step:
After that, download the little Utilitie
OpenStartMenu from
Chris'n'Soft » Download
and save it, where ever you want (for example at C:\Program Files\OpenStartMenu). Create a (Desktop-) Shortcut to the openstartmenu.exe. Now go to the properties from this Shortcut and change the Icon the way you like it.
Third Step:
When you execute this Shortcut the first time, it will promt a Dialog Box with a Security Warning Message: "Do you want to open this file?". Uncheck the Option "Always ask before opening this file"! Now this Dialog Box is disabled for OpenStartMenu.
Fourth Step:
Now pin the OpenStartMenu-Shortcut to your Superbar and you have an individual Start Button without patching the explorer.exe.
