So now what is "God mode" in windows?

Well, for starters, it's not really a mode.It is one type of secret feature of windows.

Although its name suggests perhaps even grander capabilities, Windows enthusiasts are excited over the discovery of a hidden "God Mode" feature that lets users access all of the operating system's control panels from within a single folder.

To make this folder just make "new folder" give it any name and then after name add "." and
{ED7BA470-8E54-465E-825C-99712043E01C}
Ex.-->Anyname.{ED7BA470-8E54-465E-825C-99712043E01C}
It is given in following image 

After going into that folder you will see all kinds of controls.

There are also some another folder Listed below which I found till now.
 For "Home Group"
{67CA7650-96E6-4FDD-BB43-A8E774F73A57}

"Library"
{896664F7-12E1-490f-8782-C0835AFD98FC}

"Search Result"
{9343812e-1c37-4a49-a12e-4b2d810d956b}

"Recycle Bin"
{645FF040-5081-101B-9F08-00AA002F954E}

"Don't want to open folder "
{1531d583-8375-4d3f-b5fb-d23bbd169f22}

Speech Recognition
{58E3C745-D971-4081-9034-86E34B30836A}

You can also use this folder to lock your private folder by putting your content into your private folder then rename to upward listed folder which u want.

NOTE: It may be different for different operating system but you can find above code for your os from registry .
