— The philosophy

No runtimes.
No interpreters.
One binary.

Direct Win32 calls. Total control. Nothing between your intent and the kernel — no PowerShell host, no .NET CLR, no managed scaffolding.

01 / Under the hood— Code preview

A tweak, in C.

// voidtune-c — registry tweak engine (simplified)
BOOL ApplyTweak(const Tweak *t) {
  HKEY hk;
  if (RegCreateKeyExW(t->hive, t->subkey, 0, NULL,
    REG_OPTION_NON_VOLATILE, KEY_SET_VALUE, NULL, &hk, NULL) != ERROR_SUCCESS)
    return FALSE;
  RegSetValueExW(hk, t->value, 0, REG_DWORD,
    (const BYTE*)&t->apply_val, sizeof(DWORD));
  RegCloseKey(hk);
  return TRUE;
}
// zero external dependencies. direct Win32.

02 / Motivation— Why C

Closer to the metal.

The PowerShell edition works. C lets us go further: instant startup, no .NET dependency, and direct Win32 access for precise control.

01 SPD

Instant Startup

No PowerShell, no .NET to initialize. The C binary launches in milliseconds — not seconds.

02 API

Direct Win32

Direct calls to the Windows API — registry, services, processes, drivers — with no abstraction layer.

03 SZ

Minimal Footprint

No dependencies. No runtime. No installer. A single executable with everything embedded.

04 MOD

Modular

Tweaks, diagnostics, interface, backup — each as a discrete module. Easier to extend, easier to audit.

05 GUI

Native UI

Native Win32 interface — no WPF, no XAML, no markup files travelling alongside the executable.

06 SEC

Auditable

Clean C. Every operation visible. No interpreted layer between system and code.

03 / Roadmap— No fixed deadlines

The plan.

P·01 Shipped

Architecture & Core

Project structure, build system (gcc/MinGW), Win32 framework, registry abstraction layer, CLI mode. Zero PowerShell dependency from day one.

P·02 Shipped

One-Click Optimizer

Every SAFE tweak from the main edition, ported to native C and applied in a single automatic pass — no menus to click through.

P·03 In progress

Native Interface

A native Win32 interface with the same dark Voidtune aesthetic — no XAML, no WPF, no markup. Pure GDI with custom rendering.

P·04 Planned

Feature Parity

Backup / restore, process monitor, benchmarks, service management, app installer — everything the PS edition does.

P·05 Shipped

Public Launch

VOIDTUNE One-Click is public and on GitHub. Coexists with the PowerShell (WinUI) edition. Both maintained independently.

Beyond Future

Optimization & Community

Performance profiling, community feedback, extended hardware support, continuous improvement based on real-world usage.

04 / Legal— Read this

Important notice.

01

Early software

VOIDTUNE One-Click is public on GitHub, but still under active development — the CLI optimizer is stable, while the native GUI (see roadmap) is still being built.

02

Use at your own risk

One-Click modifies the Windows registry, services, and other system settings. You are responsible for any data loss, instability, or hardware issues that may result from using the software.

03

No warranty

This software is provided AS IS, without warranty of any kind. Always create a Windows System Restore Point before applying any tweaks.
