Recommended: 8GB RAM, SSD storage for optimal performance.

Installation Steps:

1. Download the latest STX1-SystemMonitor-vX.X.X-Setup.zip from our GitHub Releases
2. Extract the ZIP file to a temporary folder
3. Right-click Setup.exe and select "Run as Administrator"
4. Follow the installation wizard prompts
5. Launch STX.1 from the Start Menu or Desktop shortcut

The installer will automatically check for and install .NET 8 Runtime if needed. For detailed instructions, visit our Installation Guide.

Windows SmartScreen may display a warning because STX.1 is a new application that hasn't established download reputation yet. This is common for indie software and does not indicate malware.

To bypass SmartScreen:

1. Click "More info" on the SmartScreen dialog
2. Click "Run anyway" button

STX.1 is open-source and you can verify the code on GitHub. We do not include any telemetry, ads, or malicious code.

Uninstallation Steps:

1. Open Windows Settings
2. Go to Apps → Installed Apps
3. Find "STX.1 System Monitor" in the list
4. Click the three dots (⋯) and select "Uninstall"
5. Follow the uninstaller prompts

This will remove the application and all stored data (including 30-day history). Your settings and preferences will also be deleted.

Game Mode automatically detects when you launch a game and optimizes system resources for maximum performance. Features include:

• Auto-Detection: Recognizes popular games and automatically activates
• FPS Overlay: F1-style telemetry display (press F2 to toggle) showing FPS, CPU/GPU usage, temps, and RAM
• Performance Profiles: Balanced, Performance, and Eco modes
• RAM Cache: Clears standby memory to free up resources
• Background Optimization: Reduces non-essential processes

You can manually enable/disable Game Mode from the main window or system tray.

STX.1 monitors your CPU and GPU temperatures in real-time and alerts you when thresholds are exceeded:

• Warning Level (80°C): Yellow notification in system tray
• Critical Level (90°C): Red notification with sound alert
• Customizable: Adjust thresholds in Settings → Alerts

Alerts help prevent thermal throttling and potential hardware damage from overheating.

STX.1 stores 30 days of system telemetry locally on your device using SQLite database. Tracked metrics include:

• CPU usage and temperature
• GPU usage and temperature
• RAM usage (physical and committed)
• Network upload/download speeds
• Disk read/write activity

View detailed charts and trends in the Historical Data section. Data is automatically purged after 30 days to save disk space.

The Browser Privacy Cleaner securely removes browsing data from popular browsers:

Supported Browsers: Chrome, Edge, Firefox, Brave, Opera

What it clears:

• Browsing history
• Cache files
• Cookies
• Download history
• Temporary internet files

Note: This does NOT delete saved passwords, bookmarks, or form data. Always close browsers before using this tool.

Temperature readings require hardware sensor support. If temperatures aren't displaying:

1. Run as Administrator: Right-click STX.1 shortcut → "Run as administrator"
2. Update Drivers: Ensure GPU drivers are up to date
3. Check BIOS: Some motherboards disable sensor reporting by default
4. Hardware Limitation: Very old hardware may not expose temperature sensors via WMI/LibreHardwareMonitor

If issues persist, check our Troubleshooting Guide or report an issue.

STX.1 is optimized for minimal resource usage. Typical usage:

• CPU: 1-3% (idle), 3-5% (active monitoring)
• RAM: 80-150 MB

If you're experiencing high usage:

1. Reduce polling interval in Settings → Performance (increase from 1s to 2-3s)
2. Disable historical data collection if not needed
3. Close unnecessary widgets or charts
4. Restart the application

Troubleshooting steps:

1. Enable Game Mode: Make sure Game Mode is active (system tray icon turns red)
2. Toggle Overlay: Press F2 in-game to show/hide overlay
3. Run as Admin: Some games require STX.1 to run with administrator privileges
4. Fullscreen Mode: Try switching between fullscreen, borderless, and windowed modes
5. Anti-Cheat Conflict: Some anti-cheat systems block overlays. This is a known limitation for competitive games like Valorant, Rainbow Six Siege

The overlay works best with DirectX 11/12 games in borderless or windowed mode.

Common solutions:

1. Update .NET Runtime: Download and install the latest .NET 8 Runtime
2. Windows Updates: Ensure Windows is fully updated
3. Reset Settings: Delete %LocalAppData%\STX1\settings.json
4. Clean Reinstall: Uninstall completely, delete %LocalAppData%\STX1, then reinstall
5. Check Event Viewer: Look for crash details in Windows Event Viewer → Application logs

If crashes persist, please report a bug with your system specs and error logs.

No. STX.1 does NOT collect any personal data, telemetry, or analytics.

We are committed to complete privacy:

• No account creation or registration required
• No network connections for telemetry
• No crash reporting to external servers
• No advertising or tracking pixels
• All data stays on your local device

The only network activity is checking for software updates (optional) and displaying this documentation. Read our full Privacy Policy.

Yes, STX.1 is completely safe.

• Open Source: Full source code available on GitHub
• No Malware: No viruses, trojans, spyware, or adware
• Signed Binary: Application is digitally signed (signature verification pending)
• Community Verified: Transparent development with community oversight

If your antivirus flags STX.1, it's likely a false positive due to the app's hardware access requirements. You can verify the source code yourself before installation.

Administrator privileges are required for certain features that access low-level hardware sensors:

• Temperature Sensors: Reading CPU/GPU temps via WMI and LibreHardwareMonitor
• Fan Speed Control: Accessing motherboard sensor data
• Performance Monitoring: Detailed process and kernel-level metrics
• RAM Cache Clearing: Flushing standby memory requires elevated permissions

STX.1 will run without admin rights but some features will be limited. We only request privileges when necessary and never abuse system access.
