Using powercfg to duplicate the currently active power scheme

I need to run a batch file, with a series of powercfg commands to duplicate the currently active scheme and rename it.

Manually, I would do something like this at the command prompt.

powercfg -getactivescheme

This would give me the GUID of currently active scheme.

powercfg -duplicatescheme <GUID obtained above> <new GUID>

Ideally, I would want to do something like this...

powercfg -duplicatescheme -getactivescheme <new GUID>

But since this isn't allowed, is there another way?

Well, first you need to pull out the GUID from the output of powercfg. This can be done with the for command:

for /f "tokens=2 delims=:(" %%x in ('powercfg -getactivescheme') do echo %%x

This will just output the GUID, you can also save it in a variable:

for /f "tokens=2 delims=:(" %%x in ('powercfg -getactivescheme') do set guid=%%x

You might want to remove extra spaces from this (here I get one space in the front of the line and another two at the end:

set guid=%guid: =%

Now that you have the GUID, you can put it into your command line above:

powercfg -duplicatescheme %guid% <new GUID>

You only need to think of a new GUID. I don't know an included commandline program which generates one for you.

NB: The code here (especially the for part) assumes that you do this in a batch file. For playing around directly on the commandline, you'd have to use %x instead of %%x in the for commands.
