Using the mentioned Start8 from Stardock is so much easier and I would think more long lived. not only does it remove the "Metro" start screen but used in conjunction with windows own "netplwiz" can remove the need to sign in as well (although you will need to sign in following any sleep or instances where the screen-saver comes into action - so safe there then). As the author states - Microsoft may alter the code in the future to eliminate the Explorer.exe scheduled event but I'm pretty sure that Stardock will keep Start8 up and running in the future!
