# Windows Reboot Monitor Setup Instructions

This guide will help you set up Discord notifications for Windows reboots due to updates, power outages, or other events.

## Prerequisites

1. **Discord Webhook URL**: Create a webhook in your Discord server
   - Go to Server Settings → Integrations → Webhooks
   - Create a new webhook and copy the URL

2. **Administrator Access**: Required to set up scheduled tasks

## Installation Steps

### Step 1: Create Scripts Directory
```powershell
# Run as Administrator
New-Item -ItemType Directory -Path "C:\Scripts" -Force
```

### Step 2: Copy PowerShell Script
1. Copy `windows-reboot-monitor.ps1` to `C:\Scripts\`
2. Set execution policy (if needed):
```powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
```

### Step 3: Configure Discord Webhook
Option A - Environment Variable (Recommended):
```powershell
# Set system environment variable
[Environment]::SetEnvironmentVariable("DISCORD_WEBHOOK_URL", "YOUR_WEBHOOK_URL_HERE", "Machine")
```

Option B - Direct parameter:
- Edit the Task Scheduler XML files to include your webhook URL in the arguments

### Step 4: Import Scheduled Tasks
```powershell
# Import startup monitoring task
schtasks /create /xml "C:\path\to\windows-reboot-task-startup.xml" /tn "Discord Reboot Monitor - Startup"

# Import shutdown monitoring task  
schtasks /create /xml "C:\path\to\windows-reboot-task-shutdown.xml" /tn "Discord Reboot Monitor - Shutdown"
```

### Step 5: Test the Setup
```powershell
# Test startup notification
C:\Scripts\windows-reboot-monitor.ps1 -EventType "startup"

# Test shutdown notification
C:\Scripts\windows-reboot-monitor.ps1 -EventType "shutdown"
```

## What You'll Get

### Startup Notifications (Green/Red)
- **Green**: Normal startup with boot reason and uptime info
- **Red**: Unexpected restart (power loss, crash, etc.)

### Shutdown Notifications (Yellow)  
- System going offline with uptime and shutdown reason

### Information Included
- Computer name
- Timestamp
- Boot/shutdown reason (Windows Update, power loss, user initiated)
- System uptime
- Startup counter

## Troubleshooting

### Check Logs
View logs at: `C:\Windows\Temp\reboot-monitor.log`

### Verify Tasks are Running
```powershell
# List scheduled tasks
Get-ScheduledTask | Where-Object {$_.TaskName -like "*Discord Reboot*"}

# Check task history
Get-WinEvent -LogName "Microsoft-Windows-TaskScheduler/Operational" | Where-Object {$_.LevelDisplayName -eq "Error"}
```

### Test Discord Webhook
```powershell
# Manual test
$webhook = "YOUR_WEBHOOK_URL"
$payload = @{content = "Test message from Windows"} | ConvertTo-Json
Invoke-RestMethod -Uri $webhook -Method Post -Body $payload -ContentType "application/json"
```

### Common Issues

1. **PowerShell Execution Policy**: Run `Set-ExecutionPolicy RemoteSigned`
2. **Network Issues**: Ensure Windows can reach Discord (discord.com)
3. **Permissions**: Run PowerShell as Administrator for setup
4. **Webhook URL**: Verify the Discord webhook URL is correct

### Event Log Monitoring
The script monitors these Windows events:
- **Event ID 1074**: System shutdown/restart
- **Event ID 6008**: Unexpected shutdown
- **Boot events**: System startup

## Security Notes

- Script runs with SYSTEM privileges for reliable monitoring
- Webhook URL is stored securely in environment variables or config
- Logs are stored in Windows temp directory
- No sensitive system information is transmitted

## Customization

Edit `windows-reboot-monitor.ps1` to:
- Change Discord message format
- Add additional system information
- Modify notification colors
- Adjust logging behavior
- Add email notifications as backup

## Uninstallation

```powershell
# Remove scheduled tasks
schtasks /delete /tn "Discord Reboot Monitor - Startup" /f
schtasks /delete /tn "Discord Reboot Monitor - Shutdown" /f

# Remove files
Remove-Item -Path "C:\Scripts\windows-reboot-monitor.ps1" -Force
Remove-Item -Path "C:\Windows\Temp\reboot-monitor.*" -Force

# Remove environment variable
[Environment]::SetEnvironmentVariable("DISCORD_WEBHOOK_URL", $null, "Machine")
```
