🛡️ Windows Telemetry Blocker

A lightweight, open-source toolkit to disable Windows telemetry and enhance privacy on Windows 10 and 11 using PowerShell scripts. Inspired by tools like ShutUp10++, but fully transparent, modular, and scriptable.

✨ Features

• Interactive Module Selection: Choose which modules to run via CLI or GUI-like menu.
• Easy Rollback: Revert changes with dedicated rollback scripts.
• Advanced Logging: Comprehensive logs, error tracking, and execution statistics.
• Modular Design: Independent modules for telemetry, services, apps, and misc tweaks.
• System Restore Points: Automatic creation before changes for safety.
• Multiple Execution Modes: Interactive, batch, dry-run, and custom profiles.
• Audit Logging: Logs to Windows Event Viewer for compliance.
• Auto-Update: Fetch latest versions from GitHub.
• Integrity Checks: Verifies script and module integrity.
• Detailed Reports: Markdown reports of changes and execution results.

⏪ Rollback

Rollback scripts are available for most modules in modules/*-rollback.ps1.

Using Rollback

• Via Launcher: Option 6 "Restore via builtin rollback system"
• Via Script: .\windowstelementryblocker.ps1 -Rollback
• Individual: Run specific rollback script, e.g., .\modules\telemetry-rollback.ps1

Rollback Coverage

• Telemetry: Removes AllowTelemetry registry value.
• Services: Sets disabled services back to Manual startup.
• Apps: No automatic rollback (app removals are irreversible; reinstall manually).
• Misc: Removes Timeline-related registry values.

Registry backups are created in registry-backups/ before changes.

📝 Logging and Reports

Log Files

• telemetry-blocker.log: Main execution log with timestamps.
• telemetry-blocker-errors.log: Error messages only.
• telemetry-blocker-stats.log: Execution statistics (start/end times, durations).
• telemetry-blocker-report.md: Detailed Markdown report of changes.

Audit Logging

With -EnableAuditLog, events are logged to Windows Event Viewer under "Application" source "TelemetryBlocker".

Reports

Post-execution, a Markdown report is generated with:

• Execution details (date, version, Windows info)
• Modules run with status and timestamps
• Summary of changes
• Errors (if any)

⚙️ Customization

Adding Modules

1. Create modules/yourmodule.ps1 with functions and return $true on success.
2. Optionally create modules/yourmodule-rollback.ps1 for rollback logic.
3. Update dependencies in the main script if needed.
4. Use Write-ModuleLog for logging (from common.ps1).

Common Functions

Located in modules/common.ps1:

• Write-ModuleLog: Logs messages with fallback.
• Set-RegistryValue: Safely sets registry values with type support.

Profiles

Customize profiles in run.bat by editing the module lists.

🔧 Troubleshooting

Common Issues

• "Access Denied": Run as administrator.
• "Script not found": Use self-healing mode in launcher.
• Modules fail: Check logs for specific errors; try rollback.
• No PowerShell: Install PowerShell or use Windows PowerShell.

Pending Reboot

If a reboot is pending, the script warns but continues. Reboot before running for best results.

Dry Run

Use -DryRun to preview changes without applying them.

Update Issues

If update fails, download manually from GitHub.
