God Mode for Windows 8 Power Users

One of the more interesting bits of functionality hidden in Windows 8 is "God Mode," a hidden menu that allows power users access to a massive selection of administrative, maintenance, and troubleshooting utilities and features. To reveal God Mode, first bring up File Explorer and then click on the View tab. Make sure that "Hidden items" and "File name extensions" are both checked.

Then, on your desktop, create a new folder, and change that folder's name to "GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}" (omitting the quotes). The folder's icon should change. Double click on it, and Explorer will present you with a ton of options to tweak your system.

Just type directly in Metro Start-up Screen

Many users are taken back by the completely new fangled screen that displays on first boot-up of Windows 8. But just thinking of it simply as a full-screen start button panel.

Just as with Windows 7's start button menu, you can simply start typing even though the search box is not visible, just type the name or a few letters of a program to display app names that match the letters you type. If what you're looking for isn't there, say, you want to run the control panel, switch the right-slide selector bar to Settings; if you're looking for a picture or doc, switch it to Files. Note that you can also search within any of the apps listed below these three choices.
