StartMenu8, a simple and free alternative that mimics the launch button in Windows 7 almost to the letter. As such, you have the section with frequently used programs, the side menu (with the exact entries as in Windows 7), the power button and the search bar.
There was a thread that had StartMenu8 listed, among a few others, but as the forum changed a bit, that and some other threads were lost.
Glad to see it brought forward again.
