35 real Windows tweaks.
Every one reversible.
Most "boosters" are a progress bar and a placebo. Nivox writes documented registry keys, service start types and power settings — tells you exactly which ones — and stores your original values first, so any change is one keypress away from being undone.
No hidden list. This is all of it.
Every tweak names the setting it touches. Nothing here disables Defender, SmartScreen, Windows Update security or any other protection — that is not optimization, that is just risk.
Interface responsiveness and disk clutter — the changes you feel within a second of logging in.
Scheduler priority, input, and the background recording most people never realise is running.
Latency work on the adapter that actually carries your traffic — detected at runtime, not guessed.
Explorer and services. The two service tweaks are trade-offs, so they are deliberately left out of the recommended set.
Documented policy keys only — the same switches an administrator would set through Group Policy.
Plans and throttling. Several of these raise power draw — the app labels which ones are desktop-oriented.
Built to tell you the truth
The hard part of a tweaking tool is not writing a registry key. It is being honest when the write fails.
A failure is reported as a failure
Exit codes and error output from netsh, powercfg and sc are checked on every call. If a command fails, you get its real message — not a green checkmark. Hibernation, for example, is re-read from the registry afterwards to confirm powercfg actually did what it claimed.
Reason: sc.exe exited with code 5: Access is denied.
Real DNS benchmarking
The DNS tweak builds actual DNS query packets, sends them over UDP to each resolver and times the replies from your connection. The numbers you see are the ones your line produced, seconds ago.
UAC, not around it
Elevation is detected at launch. When a tweak needs admin, you get the standard Windows prompt — nothing is bypassed.
Everything logged
Every apply, restore and error goes to a dated log file with the full reason and stack trace.
One file, nothing installed
A self-contained .NET 8 build. No runtime install, no service left running in the background, no scheduled task. Delete the .exe and it is gone.
Undo is the whole point
Plenty of tools "revert" by writing whatever Microsoft's default happens to be. That is not your configuration. Nivox writes back the exact value it found.
- Read firstBefore a tweak's first change, the current value is read — including whether the registry value existed at all.
- Write the backupIt is saved as JSON under %LOCALAPPDATA%\NivoxTweaks\Backups. If the backup cannot be written, the tweak is not applied.
- Apply onceThe backup is captured only on the first apply, so it always holds your true original state.
- Restore exactlyRestore rewrites that value, or deletes it again if Windows never had it. One tweak, or the whole session.

The questions everyone asks
Windows says "Windows protected your PC". Is something wrong?
No. The download is not code-signed yet, so SmartScreen warns about any new unknown publisher. Click More info → Run anyway. A signing certificate is on the list, and until then this warning is expected — be sceptical of anyone who tells you to turn SmartScreen off instead.
Do I have to install anything?
No. It is a single self-contained .exe — the .NET runtime is built in. Double-click and it runs. An optional installer exists if you prefer Start menu shortcuts and a normal uninstall entry.
Does it need administrator rights?
Only for some tweaks. User-level ones — animations, mouse acceleration, Game Mode, most privacy switches — work without it. For services, power plans and machine-wide policies the app asks you to restart it elevated through the normal UAC prompt.
How much faster will my PC actually be?
Honestly: it depends, and anyone quoting you a fixed FPS number is guessing. These tweaks remove background work, input smoothing and artificial delays. On a clean, fast machine the difference may be small; on a cluttered one it is very noticeable. What is guaranteed is that you can measure it yourself and undo anything that does not help.
Does it disable my antivirus or Windows Defender?
Never. No tweak touches Defender, SmartScreen, firewall or update security. Tools that do are trading your security for a benchmark number.
What happens to my backups if I uninstall?
They stay in %LOCALAPPDATA%\NivoxTweaks. Uninstalling does not delete them, so you can still restore tweaks afterwards. Backups are per-PC and are not synced anywhere.
