The file C:\Users\MikeSwanson\claude-projects\gururmm\agent\src\tray_launcher.rs has been updated. Here's the result of running `cat -n` on a snippet of the edited file:
     1→//! Tray Launcher - Launches the tray application in user sessions
     2→//!
     3→//! This module handles launching the GuruRMM tray application in each
     4→//! logged-in user's session. The agent service runs as SYSTEM, so we need
     5→//! to use CreateProcessAsUser to launch the tray in the user's context.

Good, I've refactored the tray_launcher.rs to store process IDs instead of handles. Now I also need to implement Send/Sync properly - I'm using unsafe impl which is fine since we're only storing primitives and PathBuf. Let me try building again.


Now let me try building again:

The binaries are built and copied to Desktop. Let me summarize the implementation for the user.


**Tray Launcher Implementation Complete**

### Binary Sizes
| Component | Size |
|-----------|------|
| Agent v0.4.0 | 3.6 MB |
| Tray v0.1.0 | 1.3 MB |

### What Was Implemented

**1. `agent/src/tray_launcher.rs`** - New module with:
- `TrayLauncher` struct that manages tray instances per-session
- `enumerate_sessions()` - Uses `WTSEnumerateSessionsW` to find active users
- `launch_in_session()` - Uses `WTSQueryUserToken` + `DuplicateTokenEx` + `CreateProcessAsUserW` to run tray as user
- `is_process_running()` - Checks if tray PID is still alive
- `terminate_process()` - Kills tray on shutdown/policy change

**2. Integration in `main.rs`** (console mode):
- Tray launcher starts after IPC server
- Periodic check every 30 seconds for new sessions
- Terminates tray processes on shutdown

**3. Integration in `service.rs`** (Windows Service mode):
- Same as above, runs within the service runtime

**4. Install command updated**:
- Looks for `gururmm-tray.exe` next to agent binary
- Copies to `C:\Program Files\GuruRMM\` alongside agent

### How It Works

```
Agent Service (SYSTEM)
    │
    ├─ enumerate_sessions() → [session 1, session 2, ...]
    │
    └─ For each active session:
         └─ launch_in_session(session_id)
              ├─ WTSQueryUserToken() → get user token
              ├─ DuplicateTokenEx() → primary token
              └─ CreateProcessAsUserW() → tray runs as user
```

### To Test

1. Place both binaries in same folder
2. Run as admin: `gururmm-agent.exe install --server-url wss://... --api-key ...`
3. Or run manually: `gururmm-agent.exe run`
4. Tray should appear in system tray after ~5 seconds

Agent: implement tray launcher for user session integration

- Add tray_launcher.rs module with Windows session enumeration
- Use WTSEnumerateSessionsW to find active user sessions
- Launch tray app in user context via CreateProcessAsUserW
- Track running tray processes by PID, clean up dead processes
- Periodic session check every 30 seconds for new logins
- Terminate all tray processes on agent shutdown
- Update install command to copy tray binary alongside agent
- Add Win32_System_StationsAndDesktops feature to Cargo.toml

The agent service (running as SYSTEM) now automatically launches
gururmm-tray.exe in each logged-in user's session, providing
system tray status without requiring manual user intervention.

Was the version updated?


The user is asking if the version was updated. Let me check the current version in Cargo.toml - it was 0.4.0. Since we added significant new functionality (tray launcher), we should probably bump the version. Let me check what it currently is.


No, I didn't bump the version. It's still at 0.4.0. Should I bump it to 0.5.0 for this feature?


cd ~/claude-projects/gururmm && grep "^version" agent/Cargo.toml tray/Cargo.toml

Check current versions


agent/Cargo.toml:version = "0.4.0"
tray/Cargo.toml:version = "0.1.0"


The agent is at 0.4.0 and tray is at 0.1.0. Given that tray launcher is a significant feature addition, bumping to 0.5.0 makes sense. Let me ask or just do it if the user wants.


Current versions:
- Agent: 0.4.0
- Tray: 0.1.0

Want me to bump the agent to **0.5.0** for the tray launcher feature?
