Method 2: Delete Custom or Built-in Power Plan Using Command Prompt

In addition to deleting custom power plan, this method also allows you to delete built-in power plans in Windows 10 / 8 / 7. Follow these steps:

1. Open the Command Prompt as administrator. Run the powercfg /list command and it will list all existing power plans in your system along with their GUIDs.

   

   If the power plan you want to delete is active, then you have to set another plan as active by running this command:
   powercfg -setactive GUID

2. Now, you can delete the desired power plan using the following command.
   powercfg -delete GUID

   

3. When it’s done, the selected power plan is deleted and you cannot use it anymore.
