1. Create a new folder or use any existing folder wherever you want the would-be GodMode folder. Right-click in Windows Explorer, select New, then click Folder.

2. Open Command Prompt and traverse directory using CD command.

3. Next, rename the folder by executing the command below :

ren <Folder Name> <Folder Name>.{ED7BA470-8E54-465E-825C-99712043E01C}

e.g., ren robie robie.{ED7BA470-8E54-465E-825C-99712043E01C}

For Windows 9x :

• Follow steps 1 & 2.
• Next execute command

          ren <Folder Name> <Folder Name>.{21EC2020-3AEA-1069-A2DD-08002B30309D}

To restore the orginal folder, run the command below :
