Launch your Registry Editor (Windows button and type “Regedit“)
Navigate to: “Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power“
Select the entry called ‘CsEnabled‘
Change the “Value data” to “1” and select “OK“ (in the case it's alreaedy 1 try 0 and reboot and again to 1)
Reboot your machine

@banicpe thx very much! Setting Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power 'CsEnabled‘ to "0" and rebooting, worked for me. I can see all Advanced Energy Options now! Great!

Anyone knows why MS hid those settings in the first place? Is it dangerous to fiddle around with them (e.g. with processor performance settings)?

@banicpe @ar-ml and all others who will landing to this page from StackOverflow or google

also helpful
export
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings
and change all
"Attributes"=dword:00000001
to
"Attributes"=dword:00000000

and import PowerSettings back

I have written my own version which works with PowerShell 7 and every Windows version: Unlock-PowerCfg.ps1

# Unlock Power Plans by disabling "Connected Standby"
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power' -Name 'CSEnabled' -Value 0 -Force

# Unlock hidden options
$PowerSettings = Get-ChildItem -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings' -Recurse -Depth 1 | Where-Object { $_.PSChildName -NotLike 'DefaultPowerSchemeValues' -and $_.PSChildName -NotLike '0' -and $_.PSChildName -NotLike '1' }
ForEach ($item in $PowerSettings) { Set-ItemProperty -Path ($item).Replace('HKEY_LOCAL_MACHINE','HKLM:') -Name 'Attributes' -Value 2 -Force }

@Velocet, small fix:

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power' -Name 'CSEnabled' -Value 0 -Force
    # Unlock hidden options
    $PowerSettings = Get-ChildItem -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings' -Recurse -Depth 1 | Where-Object { $_.PSChildName -NotLike 'DefaultPowerSchemeValues' -and $_.PSChildName -NotLike '0' -and $_.PSChildName -NotLike '1' }
    ForEach ($item in $PowerSettings) { Set-ItemProperty -Path ($item).Name.Replace('HKEY_LOCAL_MACHINE','HKLM:') -Name 'Attributes' -Value 2 -Force }

god thank you @Velocet @nick4fake guys!!!

Thanks @Velocet, your script actually works WIN 11 also, your amazing

what would i change to DISABLE all advanced power settings?

Instead of enable all options you can use Power settings GUI editor PowerSettingsExplorer

At least for my solution you don’t enable them: All settings become visible. Thats it.

I also wouldn’t download something from a random mediafire link posted on the internet… 🤨

Sorry, I have updated link to forum thread instead of direct zip

Could someone explain the basics to me? Do you have a video explaining how to install? Or is it just right-clicking and running in PowerShell?

@lucr80 Just copy those lines and paste in a PowerShell.
