## Overview


`elevate-ti` is an ergonomic Windows systems library designed to elevate privileges to `NT SERVICE\TrustedInstaller`. It acquires primary tokens via chained impersonation, navigates Session 0 isolation, and supports launching processes either onto an active interactive desktop (`WinSta0\Default`) or within headless background sessions (CI, services, and tasks).

## Architecture Flow


```text
Caller (Admin)
  │
  ├─> 1. Enable SeDebugPrivilege & SeImpersonatePrivilege
  ├─> 2. Ensure TrustedInstaller service is running (SCM)
  ├─> 3. Impersonate SYSTEM (via winlogon.exe or Session 0 SYSTEM process)
  │     └─> Duplicate TrustedInstaller Primary Token
  │     └─> Optionally bind Token to target Session ID (Caller/Interactive/None)
  │
  └─> 4. Spawn target process (Interactive Desktop or Headless)
```

## Quickstart


Add `elevate-ti` to your `Cargo.toml` by running:

```bash
cargo add elevate-ti
```

### Automatic Self-Relaunch


```rust
use elevate_ti::{status, relaunch, ElevationStatus};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    if status()? == ElevationStatus::RequiresElevation {
        relaunch()?;
        return Ok(());
    }

    println!("Running with TrustedInstaller privileges!");
    Ok(())
}
```

### Spawning an Elevated Child Process


```rust
use elevate_ti::elevated_command;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    elevated_command()?
        .exe("%SystemRoot%\\System32\\cmd.exe")
        .args("cmd.exe /k whoami /groups")
        .spawn()?;

    Ok(())
}
```
