One button
It checks your PC, saves how it was, fixes what is safe to fix, verifies it worked, and shows you the result.
OpenBX
Your PC can run better. One click tells you.
OpenBX looks at how your computer is set up, fixes only the safe things, and tells you what it did. If you do not like it, you can undo it whenever you want.

( 01 ) — What it doesIn plain words ✦
Two questions, two answers.
Most programs that promise to “speed up your PC” put hundreds of checkboxes in front of you, with names that mean nothing. Or they copy tips from a video, without knowing whether they work.
OpenBX answers only two questions: can this computer be improved, and what do I press. Press SCAN, look at the score, press OPTIMIZE. That is the whole thing.
If you are curious about what changed, a Details button shows you line by line. If you are not, you can ignore it forever.
( 02 ) — Why trust itNo magic, only things you can check ✦
It does a few things, and shows its work.
The score is not made up
It is the number of settings put right divided by the settings your PC can actually have. No FPS promises, no percentages pulled out of thin air.
You can always go back
Before changing anything, OpenBX writes down how it was. Restore was designed in from the start, not bolted on as damage control.
It ignores what does not apply to you
If a change makes no sense on your hardware or your version of Windows, it disappears from the list and does not count against your score.
Modes for gaming
Competitive, Balanced, Streaming or Default. It also finds the games you installed through Steam, Epic, Ubisoft Connect and Xbox.
It asks you for nothing
No account, no email, no statistics sent anywhere. It works without internet: the only connection is an optional update check.
( 03 ) — What it will never doThe rules I set myself ✦
Things this program refuses to do.
An optimizer can do real damage. That is why some things are ruled out from the start, not switched off somewhere in the settings:
- It does not touch your connection: no DNS, IP, gateway or network adapters.
- It does not promise FPS or latency gains without a real measurement.
- It does not disable Windows Security or Windows Update.
- It does not apply irreversible changes without asking you first.
- It does not include the “tricks” going around YouTube and TikTok that do nothing.
( 04 ) — What it looks likeReal screens from the app ✦
Six screens in total. You have just seen the first.
( 05 ) — How to install itUnder a minute ✦
Installing, step by step.
Download the installer
The button above takes you to the downloads page. Take the file ending in _x64-setup.exe.
Open it
Double-click the downloaded file and follow the installer. It installs for your Windows user only.
Start OpenBX from the Start menu
Find it among your programs, like any other app. On first launch, press SCAN.
If Windows asks permission, confirm it
Some changes need administrator rights: that is the normal Windows prompt, and it only appears when it is actually needed.
Windows may show a blue warning (“Windows protected your PC”). That happens because the installer is not yet signed with a paid certificate, not because the file is dangerous: click “More info”, then “Run anyway”. If you would rather not take my word for it, the code is public and you can build it yourself.
( 06 ) — Requirements
This is all you need.
- Windows 11, or Windows 10 from version 2004 onwards
- A 64-bit PC
- About 20 MB of free space
- No internet connection to use it
Give it a try.
It is free, it is open source, and if it does not convince you it uninstalls like any other program — leaving your PC as it was.
