Short answer: it changes Windows settings, never your games, and every change can be
undone. The longer answer is below, including the one thing we will not promise you.

What it does
What MizTweakz changes
MizTweakz applies 525 changes to Windows settings: registry values, background
services, scheduled tasks, pre-installed Store apps, and power and network settings.
They are the same changes you could make by hand, collected in one place with a
switch next to each one.
No file in a game folder is written, patched or replaced. The app reads Fortnite's install path for exactly one purpose: to show the game's own icon in the interface.
It does not inject into processes
There is no code anywhere in the app that writes into another program's memory or hooks into a running game. Nothing attaches to your game while you play.
It does not bundle third-party tools
No drivers, no kernel components, no repackaged utilities from somewhere else. It uses Windows' own interfaces to change Windows' own settings.
It does not keep your tweaks on disk
Paid tweak definitions arrive from the server after you sign in and are held in memory for that session only.
Undo
Every change can be reversed
Three ways out, in increasing order of bluntness:
Revert a single tweak. Every applied tweak has a revert next to it.
Revert a whole category. Undo all 43 network tweaks at once if your ping got worse instead of better.
Roll back the machine. The app can create a Windows restore point before it changes anything, from any category header or the Restore points tool.
The NVIDIA graphics profile is undone differently and deliberately so: instead of
reversing each value, it imports NVIDIA's own stock Fortnite profile. A half-finished
revert cannot leave your driver in a state nobody designed.
Anti-cheat
What we will not promise you
Plenty of sites in this category will tell you their software is guaranteed safe with
every anti-cheat. We are not going to, because nobody outside Riot, Epic or Valve can
promise that about software they do not control.
What we can tell you precisely:
The tweaks change Windows, not your game. Nothing is written into a game
folder and nothing attaches to a running process, which is what anti-cheat systems
are built to detect.
The crosshair overlay is the one thing to check first. It draws on top of your
game, and some anti-cheat software disallows overlays. Check your game's rules before
using it competitively. The app tells you the same thing on the crosshair screen.
If you play something with a strict overlay policy, use everything else and leave the
crosshair off. Nothing else in the app puts anything on your screen while you play.

Frequently asked questions
Safety, bans, reversibility and what happens if something goes wrong
The tweaks change Windows settings and never touch your game files or running processes, which is what anti-cheat systems look for. The one thing to check is the crosshair overlay, because some anti-cheat software disallows overlays. Check your game's rules before using it competitively, and leave it off if you are unsure.
Revert it. Every applied tweak can be undone individually, a whole category can be reverted at once, and the app can create a Windows restore point before it changes anything so you can roll the machine back entirely.
Most tweaks write to the registry, Windows services and scheduled tasks, and Windows requires administrator rights for all three. The installer asks once and the app asks each time it launches.
414 of the 525 are labelled safe and 111 are labelled caution, and the app shows you the label before you apply anything. Caution does not mean dangerous, it means the tweak turns off something you might actually use. Disabling Bluetooth services is sensible on a desktop and wrong on a laptop with wireless headphones.
Individually, mostly very little. The app rates 391 of the 525 as low impact, 108 as medium and 26 as high. The gain comes from applying a lot of them together, and it is larger on a machine carrying years of background software than on a clean install.
Yes. Windows 10 and Windows 11, on desktops and laptops. Results vary with your hardware and with how much is already running in the background.
