Prospira Tweaks
Launches 1 December 2026
Over 250 tweaks, each explained before it runs. Undo puts back what you had.
Getting started
What happens the first time you open the app.
Run the installer, then sign in. Prospira needs Windows 11, 64-bit.
Pick FPS, lower input lag, a quiet Windows or privacy. Windows saves a restore point too.
Each tweak says what it changes before it runs. Undo puts back what you had.
Entry is free forever. You pay only for Game Mode, BIOS, Advanced and NVIDIA tuning.

A specialist tunes your PC remotely while you watch.
Six straight answers.
Windows 11, 64-bit. The installer stops on older Windows, Windows 10 included.
You sign in with Discord on every plan, the free one included. There is no separate password, and Entry never asks for a card.
It is signed, so Windows shows who published it before it runs.
Some antivirus programs still flag apps that change the registry and services. That is a guess about what the app does, not a virus. We would rather tell you now than have it surprise you halfway through the install.
Flip the same switch back: Undo puts back exactly what the setting held before Prospira, and Settings has Undo all for everything at once. The few actions that cannot be undone, like cleaning files or uninstalling a program, say so and ask first.
The app also saves a Windows restore point while you set it up, a fallback for system settings.
Because a lot of what circulates for free stopped working years ago. Tweaks get copied from post to post since Windows 7, and plenty of them write to registry keys Windows 11 no longer reads. The file runs, reports success, and changes nothing.
Every tweak here is checked against the current Windows build before it ships, and checked again when a feature update changes what a setting does. And when one turns out to be the wrong one for your machine, a Discord ticket puts a person on the other end, seven days a week.
WinUtil can undo most of its tweaks, but it writes back Windows’ defaults from its own list rather than the values your PC had, and it cannot tell its changes from yours. AtlasOS is a modified Windows image: undoing it means reinstalling the system, and until then you are on a build Microsoft never shipped.
Live CPU, GPU and RAM load and temperatures show what your machine is doing. The paid plan reaches what a script cannot: BIOS settings on supported boards.
No. Every licence covers one PC and one Windows install, on every plan, free one included.
Changing computer is not buying again. Release the old PC from your account page, pay the release fee, and the next machine you sign in on takes the slot.
The app does not inject into a game, read its memory or draw an overlay. Game Mode raises the running game’s priority through Windows itself and stops if the anticheat refuses. Game Profiles writes Fortnite’s settings file only while the game is closed. The rest are Windows settings you could change yourself: the registry, services and BIOS.
We will not promise you a guarantee: no anticheat vendor certifies third-party tools. We can tell you exactly what gets changed: see what is inside Advanced.
