How to unlock additional Windows 10 power plan settings

NOTE: Making changes to your registry can have serious implications. Before making any changes to your registry, we strongly recommend creating a back-up of the registry, which you can restore in the unlikely event anything goes wrong. Find steps on how to back-up the registry, here

    Press and hold the 'Windows' and 'R' key on your keyboard, or right-click on the Start menu button and choose 'Run'.
    When the 'Run' prompt appears, type "regedit" (without quotes) and then press enter on your keyboard, or hit the 'Ok' button.
    In the left hand pane of the Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
    Locate the item entitled CsEnabled, and double-click on it.
    In the next window that appears, change the Value data field from 1 --> 0.
    Click 'OK' to confirm your choice, then restart your computer.
    You should now be able to proceed with the steps from our PC Optimization Guide for Windows, under the Adjust Power Options section, from Step 3.

Step 1 - powercfg
There is a command in Windows, powercfg, that (among a lot of other things) can be used for setting the power plan on the pc, i.e. to change to "High performance" or what is desired.

What I did was to run the command "powercfg /l" in a command prompt, and it provides a list of all the available plans. It looks something like this in my setup

C:\Users\Torsten>powercfg /l

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced) *
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance)
Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver)

And then it is possible, from the command prompt, to select any power scheme by the command "powercfg /s GUID", so e.g. "powercfg /s 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c" would select High performance.

Step 2 - create shortcut
I used this to create a desktop shortcut for starting Pianoteq, but instead of just opening Pianoteq, the shortcut will first change the power scheme to "High performance", then open Pianoteq, and when Pianoteq is closed, it switches to "Balanced".

I achieved this by creating a new shortcut (rightclick on the desktop, select "New --> Shortcut"), and then opening the shortcut properties.

In target I wrote

C:\Windows\System32\cmd.exe /c "C:\Windows\System32\powercfg.exe -s 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c && "C:\Program Files\Modartt\Pianoteq 5\Pianoteq 5.exe" && C:\Windows\System32\powercfg.exe -s 381b4222-f694-41f0-9685-ff5bb260df2e"

Please make sure that you find your own GUID values and insert, and also make sure that you point correctly to the Pianoteq executable. It got a little complicated how to call powercfg, this worked, and I am not sure if it can be done simpler, and did not invest more time in further investigation once I achieved what I intended. Suggestions are welcome.

Just to make it look nicer I also changed the shortcut icon (click the "Change icon" button, and navigate to the Pianoteq executable and select the icon).
