Start Killer is a small utility used to remove that pesky Start Button from your Windows OS! This application can remove the Start Button from your taskbar and also disable the Metro UI in Windows 8.
Settings: Writes Settings to Application Folder
Tested: Portable
System Requirements: Windows XP, Vista, 7, 8 (32/64 bit) - 32 bit version does not work on 64 bit
Uses a tray icon, which, in my opinion, does not make it stealth.
