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 }

@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)?
