Though we should never underestimate Microsoft's ambitions, this hidden feature has useful, if less grandiose value. This feature allows you to get to an extended Control Panel and see, adjust virtually all Windows settings in one place.

Ina Fried, who blogs at cnet.com's "Beyond Binary" site http://news.cnet.com/beyond-binary, explains how:

"By creating a new folder in Windows 7 and renaming it with a certain text string at the end, users are able to have a single place to do everything from changing the look of the mouse pointer to making a new hard-drive partition.

The trick is also said to work in Windows Vista, although some are warning that although it works fine in 32-bit versions of Vista, it can cause 64-bit versions of that operating system to crash.
To enter "GodMode," one need only create a new folder and then rename the folder to the following:
GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}
Once that is done, the folder's icon will change to resemble a control panel and will contain dozens of control options. I'm not sure it's my idea of playing God, but it is a handy way to get to all kinds of controls."
