Fair. That sentence describes most of what should never be run on a PC. So here is what this one is, how to check it yourself before paying, and the full list of what it will not touch.
None of these need a key, an account or a card.
The whole thing is one readable PowerShell file at omnidx.net/tune/omnidx.ps1, and the one-line bootstrapper at omnidx.net/go.ps1. Every service, task, app and registry key it touches is listed in it with the reason. There is no compiled part, no second download, nothing obfuscated. The key is what makes it run; the code was never the secret.
Free, no key. It reads your PC the way the tune does and counts your processes, then stops without changing anything. Watch what it says it found; if it has your machine right, it will cut around it right.
$env:OMNIDX_MODE='report'; irm omnidx.net/go.ps1 | iexOpen Resource Monitor's network tab while it runs. You will see two requests to omnidx.net (the config and the script) and, if a licence server is configured, one to it with your key and the PC fingerprint. That is all. The report stays in C:\OmniDx. And every service, task, app and value it touches is listed, generated from the script itself.
A PowerShell script that does, in one run and with a record, what a careful person would do by hand over an afternoon with Task Manager, Services, Settings and powercfg: turn off what runs for Microsoft rather than for you, set a power plan that keeps the CPU awake, tune the network adapter for latency, and set three per-game flags Windows never sets on its own. Then it writes you a BIOS checklist, because the biggest gain on most PCs is below Windows and no script can flip it for you.
It is not a driver, a kernel module, an overlay, a "booster" that stays resident, or a thing that injects into games. It does not overclock anything, does not touch voltages, does not flash your BIOS, and does not turn off anything that protects you. It is also not magic: if your GPU is the bottleneck, fewer processes will not change your frame rate, though your frame times will get flatter.
Because stopping a service, disabling a scheduled task, changing a power plan and writing to HKLM all need them. There is no way to do this job without them, which is exactly why you should read the file before you let it. It asks Windows for the rights itself, through the normal prompt, so you see the request.
Because it took a long time to get right — which services a laptop needs, which anti-cheat breaks if you touch what, what the 2013 tweaks do to a 2025 PC — and because a key is what lets one person's purchase be one person's. The price is one you can pay without asking anyone, once.
A tool that only lists what it does is hiding the other list. Here is the other list.
Your key, a fingerprint of the machine — a hash of the board serial, the system id and the CPU id, which identifies the PC without describing it — and the CPU and GPU names so your own machines can be told apart. Only when a licence server is configured; otherwise the key is checked and bound on the PC itself.
What it found, what it changed, the process counts and the BIOS checklist are written to C:\OmniDx and nowhere else. Nothing about your PC is uploaded.
Nothing stays running, so nothing can phone home later. The only process of ours you will ever see is the PowerShell window while it runs. One exception, disclosed: a scheduled task that runs once at your next sign-in, counts processes, writes the number to C:\OmniDx\after-restart.txt and deletes itself. It sends nothing anywhere, and -NoAfterCount skips it.
Your PC stays tuned, because the changes are ordinary Windows settings and not a program that needs us. The undo is a file on your disk that needs no key and no internet. The report and the BIOS checklist are text. A key already bound to your PC keeps working when the licence server cannot be reached, by design.
The only thing you would lose is the ability to fetch a newer version with the one-line command — and you can save the script itself today from omnidx.net/tune/omnidx.ps1 and run it with -Key whenever you like.
One person, building this on their own. Not a company, not a team, and I am not going to pretend otherwise with a fake "About us" page and stock photographs of an office. That is the honest weakness of buying from me: there is no support department behind this, and if I am asleep your email waits until morning.
It is also the honest strength. Nobody above me needs a growth number next quarter, which is why there is no subscription, no account, nothing installed and nothing left running — those things exist to hit targets I do not have.
