There’s no Start menu like the old Start menu. You can choose from dozens of Start menu replacements -- our own Serdar Yegulalp has nine options in this Test Center analysis -- but the one I keep coming back to is Stardock’s Start8.
Start8 actually works better than the Windows 7 Start menu. Try it free for 30 days. Keep it, and Start8 will set you back $4.99.
While you’re at it, seriously consider getting Stardock’s ModernMix -- there’s an offer to download it at the same time as Start8. You may want to run a Metro app some day (forgive my blasphemy), and the way to do it is inside a window on your desktop, the ModernMix way.
