It has been around for a while. There was a similar "mode" in Xp, but with, of course, a different string.
All of the tasks in the "God Mode" list are already available in Control Panel. There is not a single new or hidden tweak here.
But if you like to play, there are quite a few more such strings in the registry. I have read that it is dangerous to use these in 64Bit. But I have tried them without consequences. - Have fun:
To make it work, create a new folder with any name, then a period, then one of the text strings below.
For example, the first one could be a folder named thanks.{00C6D95F-329C-409a-81D7-C46C66EA7F33}
Here's the list of strings:
{00C6D95F-329C-409a-81D7-C46C66EA7F33}

Not forgetting, of course Godmode itself, use the string in the OP
