How to Use Windows Ultimate Performance Script
This guide explains how to use Recruit's Windows Power Script to unlock the hidden Ultimate Performance power plan, set it active, and remove every other power plan so Windows keeps using the right one after restart.
What the Script Does
Windows includes an Ultimate Performance power plan on supported editions, but it is often hidden by default. This script uses Windows powercfg commands to reveal it, activate it, and remove other power plans so Ultimate Performance is the only plan left.
This is useful because Windows can bug out after restart: it may show the selected plan in Power Options but behave like another plan in the background. Keeping only Ultimate Performance avoids that mismatch.
Before You Run It
- Use Windows 10 or Windows 11.
- Save open work before changing power settings.
- Run the script as administrator.
- Understand that this removes the default Balanced, Power Saver, and High Performance plans from the visible power plan list.
- Do not run scripts from random sources unless you trust and understand them.
- If you use a laptop, expect higher battery drain and more heat on performance plans.
Step-by-Step: Enable Ultimate Performance
Run as administrator. This is required because Windows power schemes need admin permission.powercfg to duplicate or reveal the Ultimate Performance scheme.How to Verify the Active Power Plan
After running the script, open Windows Power Options and check that Ultimate Performance is selected and the other plans are gone. You can also verify with Command Prompt:
powercfg /getactivescheme
If it worked, the active scheme should show Ultimate Performance.
Common Problems and Fixes
powercfg may fail.powercfg -restoredefaultschemes, then pick the plan you want.FAQ
Will this increase FPS?
It can help consistency by reducing power-saving behavior, but it is not magic. GPU, CPU, thermals, game settings, and drivers still matter.
Is Ultimate Performance safe?
Yes, but it may use more power and create more heat because Windows is less aggressive about saving energy.
Why remove the default plans too?
Because Windows can sometimes show the selected plan after restart while not actually behaving like it. Removing the other plans keeps the system from drifting back to another power behavior.
Should every gamer use it?
Desktop gaming PCs can benefit from it. Laptop users should be more careful because battery life and heat matter more.
