System Add or Remove "Processor performance boost mode" in Power Options on Windows 11

dacrone · 2026-06-16T15:31:39-0400

this PowerShell will unlock ALL advanced power options, including this one.. for interested parties

Code:

#Requires -RunAsAdministrator

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

# Get Power Settings entries and add/set 'Attributes' to 2 to unhide
$PowerCfg = (Get-ChildItem 'HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings' -Recurse).Name -notmatch '\bDefaultPowerSchemeValues|(\\[0-9]|\b255)$'
foreach ($item in $PowerCfg) { Set-ItemProperty -Path $item.Replace('HKEY_LOCAL_MACHINE','HKLM:') -Name 'Attributes' -Value 2 -Force }

It might be related to another option

Afraid this tutorial no longer works on current Windows builds. It will no longer add the option to my machines.

It depends on if supported by your proccessor, but it was available in W11 build 26300.8687 Experimental for me.

I use to have it on my machines but it vanished on them and can no longer be reset now it seems. I'm on latest Beta and RP builds.

Use the powershell to unhide everything. It should show again.

Thanks, I'll give it a shot tomorrow morning.

Adding it works on mine (I use my own .reg file for the ones I want)., but I set the registry default values to 2 to reveal them in Power options. Since they are lost by in-place upgrades, I have a power shell script that scans the appropriate keys in the registry for the value of two, and generates a reg file ready for loading.

Code:

Function SavePwrExtensions {

    # saves manually made registry mods made to reveal power settings in power Option profiles (by setting attributes to 2)

    $ofile="PwrExtensionsAdd.reg"

    $pwrmstr = "HKLM:\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00"


    "Windows Registry Editor Version 5.00`n" > $ofile

     get-Childitem -Path $pwrmstr | get-ItemProperty | Where-Object {if ($_.Attributes -eq 2) {"#  "+ $_.Description >> $ofile; "["+$_.pspath.substring(36)+"]" >> $ofile; '"Attributes"=dword:00000002' >> $ofile; "" >> $ofile }

     }

It looks like the original @Brink instruction option 1) actually removes it from power config (sets it to 0 instead of 2), or am I missing something?

EDIT:

Anyhow here is the output of my above script (the power config options I find most interesting/useful:

0 or 2 should add it, and 1 should remove it. 0 is what's set when adding it using the attrib command.

Well just tried this powershell command but this failed as well. Decided to ask Co-pilot and this is what it told me:

Why the setting no longer works

1.

Starting with Windows 11 (and fully enforced by 23H2+), Microsoft shifted CPU control to:

Hardware Autonomous Mode
Energy Performance Preference (EPP)
Energy Performance Bias (EPB)
HWP (Intel) / CPPC2 (AMD/ARM)

These mechanisms override the old “Processor performance boost mode” policy.

The old setting controlled:

Code

ProcessorPerformanceBoostMode<br>
But modern CPUs use hardware-managed boosting, not OS-managed boosting.

So Windows simply ignores the policy.

Odd. I just tested on a pc and it showed, along with the rest of the hidden. Even laptop (battery, etc) only power options showed on the desktop.

FrancoDT · 2026-06-17T10:34:02-0400

Correction, it did add this and several other settings now but from what Co-pilot says they are ignored.

dacrone · 2026-06-17T10:38:05-0400

There should be a boost policy now too. What percentage is that dropdown set to?

There's all kinds of settings now but my Processor Performance boost mode shows my original settings before they disappeared. However Co-pilot says that is no longer used so not sure it even matters.

2.

You can still add:

Code

{be337238-0d82-4146-a960-4f3749d470c7}<br>
into Power Options, but:

Windows 11 23H2+ does not query the value
The kernel’s power manager no longer exposes the callback
The CPU driver (intelppm.sys / amdppm.sys / acpi.sys) no longer maps it to hardware registers

This is why changing it does nothing.

3.

EPP is the real control mechanism now.

Examples:

0 = maximum performance
255 = maximum efficiency
Balanced plans usually sit around 60–120
High Performance sets EPP to 0
Power Saver sets EPP to 200+

EPP is what actually influences boost behavior now—not the old Boost Mode toggle.

4.

Modern CPUs (Intel 12th–15th gen, AMD Zen 3–5, ARM X1/X1E/X1P) use:

Intel Speed Shift (HWP)
AMD CPPC2
Qualcomm Oryon/Adreno CPPC

These systems decide boost behavior in hardware, not Windows.

Windows only provides a hint via EPP.

The old Boost Mode setting was designed for pre‑HWP CPUs (Skylake era).It is obsolete.

5.

Even if you force‑enable the setting with:

Code

powercfg -attributes SUB_PROCESSOR be337238-0d82-4146-a960-4f3749d470c7 -ATTRIB_HIDE<br>
The UI appears, but:

The slider does nothing
No kernel event fires
No ACPI call is made
No CPPC request is updated

It’s a zombie setting.

dacrone · 2026-06-17T10:54:25-0400

Processor Performance Boost Policy is further down the list Past Boost Mode

This one I take it

System Add or Remove "Processor performance boost mode" in Power Options on Windows 11

Add "Processor performance boost mode" to Power Options

Remove "Processor performance boost mode" from Power Options
