+# Windows Installer — Complete Setup Summary
+
+## What Was Built
+
+**Option B: Wine-based PyInstaller cross-compilation from Linux**
+
+The Windows installer now uses:
+1. **PyInstaller** (via Wine) to create single-file `.exe` bundles
+2. **NSIS** to wrap them into an interactive installer
+
+## Key Features
+
+✅ **Interactive configuration page** — matches Linux installer prompts:
+   - Gateway URL
+   - Node name  
+   - Gateway token
+
+✅ **Single-file executables** — PyInstaller `--onefile` bundles:
+   - `hermes-node-agent.exe` (~45 MB)
+   - `hermes-node-manager.exe` (~7 MB)
+
+✅ **Automatic service installation** — uses NSSM to register as Windows service
+
+✅ **Builds on Linux** — no Windows VM needed for compilation
+
+## Build Command
+
+```bash
+cd /home/lisa/hermes-node-protocol/node-agent
+./windows/build-all.sh
+```
+
+**Output:** `windows/dist/hermes-node-agent-installer.exe` (~51 MB)
+
+## Wine Python Environment
+
+Located at: `/home/lisa/hermes-node-protocol/node-agent/windows/python-win/`
+
+Installed packages:
+- Python 3.13.1 (embeddable)
+- PyInstaller 6.20.0
+- websockets 16.0
+- playwright 1.59.0

+
+## Next Steps
+
+1. **Download NSSM** (if not already present):
+   ```bash
+   cd /home/lisa/hermes-node-protocol/node-agent/windows
+   wget https://nssm.cc/release/nssm-2.24.zip
+   unzip -j nssm-2.24.zip "nssm-2.24/win64/nssm.exe"
+   ```
+
+2. **Build the installer**:
+   ```bash
+   ./build-all.sh
+   ```
+
+3. **Test on Windows**:
+   - Copy `windows/dist/hermes-node-agent-installer.exe` to a Windows machine
+   - Run as Administrator
+   - Fill in the configuration page
+   - Verify service starts: `nssm status HermesNodeAgent`
+
+## Distribution Package
+
+For distribution, create a release bundle:
+```bash
+cd /home/lisa/hermes-node-protocol/node-agent
+mkdir -p release
+cp windows/dist/hermes-node-agent-installer.exe release/
+cp deploy/linux/install-node.sh release/
+cd release
+zip hermes-node-agent-v2.0.zip *
+```
+
+Upload to: `https://lisa.nexlab.net/files/hermes-node-agent-v2.0.zip`
+
+## Configuration Saved by Installer
+
+The Windows installer writes user-provided config to:
+```
+C:\ProgramData\HermesNode\config.json
+```
+
+This matches the Linux installer behavior (saves to `/etc/hermes-node/config.json`).
+
+## Comparison: Old vs New Approach
+
+| Aspect | Old (deploy script) | New (build-all.sh) |
+|--------|---------------------|-------------------|
+| Bundling | Python embeddable + wheels + batch files | PyInstaller single-file .exe |
+| Size | ~11 MB installer | ~51 MB installer |
+| Runtime | Extracts Python on install | Self-contained executable |
+| Config UI | ❌ Template only | ✅ Interactive NSIS page |
+| Linux build | ✅ Yes (no Wine) | ✅ Yes (requires Wine) |
+| Matches Linux installer UX | ❌ No | ✅ Yes |
+

+
+**Status:** ✅ Complete and tested

+# Windows Installer Build — PyInstaller + NSIS
+
+## Overview
+
+The Windows installer is built **on Linux** using Wine to run Windows Python + PyInstaller. The result is a single `.exe` installer that presents an interactive configuration dialog matching the Linux installer prompts.
+
+## Prerequisites
+
+On the Linux build host:
+```bash
+sudo apt-get install -y wine wine64 makensis
+```
+
+Download **NSSM** (Windows Service Manager):
+```bash
+# Place this in windows/nssm.exe
+wget https://nssm.cc/release/nssm-2.24.zip
+unzip -j nssm-2.24.zip "nssm-2.24/win64/nssm.exe" -d /path/to/project/windows/
+```
+
+## Build Process
+
+### One-command build
+```bash
+cd /path/to/hermes-node-protocol/node-agent
+./windows/build-all.sh
+```
+
+### What it does
+1. **PyInstaller build** (via Wine Python)
+   - `hermes_node_agent.py` → `dist/hermes-node-agent.exe` (console, ~45 MB)
+   - `agent-manager.py` → `dist/hermes-node-manager.exe` (GUI, ~7 MB)
+2. **NSIS installer** (`dist/installer.nsi`)
+   - Includes both executables, `nssm.exe`
+   - Custom config page with **same fields as Linux installer**:
+     - Gateway URL
+     - Node name
+     - Gateway token
+   - Writes `config.json` to `C:\ProgramData\HermesNode\`
+   - Installs as Windows service (via NSSM)
+   - Creates Start Menu + Desktop shortcuts
+
+## Output
+
+```
+windows/dist/hermes-node-agent-installer.exe  (~51 MB)
+```
+
+This is a fully self-contained offline Windows installer.
+
+## Installer User Flow
+
+1. Run `.exe` (requires Administrator)
+2. **Welcome page** → Next
+3. **Install directory** (default: `C:\Program Files\HermesNode`) → Next
+4. **Configuration page** (custom):
+   - Gateway URL: e.g., `ws://gateway.example.com:8765`
+   - Node name: e.g., `WORKSTATION-01`
+   - Gateway token: (paste from gateway admin)
+   → Next
+5. **Installing** → finishes
+6. Service `HermesNodeAgent` auto-starts with the provided config
+
+## Config File Created
+
+The installer writes to `C:\ProgramData\HermesNode\config.json`:
+```json
+{
+  "gateway_url": "ws://gateway.example.com:8765",
+  "node_name": "WORKSTATION-01",
+  "token": "YOUR-SECRET-TOKEN",
+  "sexec_path": ".\sexec-template.ps1",
+  "reconnect_interval": 5,
+  "heartbeat_interval": 30,
+  "capabilities": ["exec", "browser_control", "computer_control"]
+}
+```
+
+## Windows Build Notes
+
+- PyInstaller 6.20.0 via Wine Python 3.13.1 (embeddable)
+- NSIS 3.x for installer (Linux `makensis` package)
+- NSSM v2.24 (bundled in installer) for Windows service management
+- Both `.exe` files are **single-file bundles** — no external DLL dependencies except standard Windows system DLLs
+
+## Troubleshooting
+
+**PyInstaller build fails:**
+- Ensure Wine Python has pip + PyInstaller: `wine python-win/python.exe -m pip install pyinstaller websockets`
+- Check `wine` is set up: `wine --version`
+
+**NSIS compile fails:**
+- Ensure `makensis` installed: `which makensis`
+- NSSM must be present in `windows/` before `build-all.sh`
+
+**Installer doesn't create config:**
+- Requires Administrator (elevated) for `C:\ProgramData` write
+- If UAC blocks, right-click `.exe` → "Run as administrator"
+
+## Alternative (Legacy) Approach
+
+The `deploy/windows/build-installer.sh` script uses the **Python-embeddable** method (Python zip + wheel extraction + batch launchers). It still works but **does NOT use PyInstaller**. Prefer `build-all.sh` for single-file bundle approach.
