📦 Installation

1. Download the tool:

   git clone https://github.com/your-username/vs-telemetry-disable.git
   cd vs-telemetry-disable

2. Or download as ZIP:

   • Click "Code" → "Download ZIP"
   • Extract to your desired location

🚀 Usage

Quick Start

1. Right-click on Launcher.bat and select "Run as administrator"
2. Follow the interactive prompts
3. The launcher will automatically detect your PowerShell version and run the appropriate script

Command Line Usage

Basic Usage (Disable telemetry)

# PowerShell 7
.\script\off_telemetry_ps7.ps1

# PowerShell 5
.\script\off_telemetry_ps5.ps1

Create Backup First (Recommended)

# Create backup before making changes
.\script\off_telemetry_ps7.ps1 -CreateBackup

# Create backup to specific location
.\script\off_telemetry_ps7.ps1 -CreateBackup -BackupPath "C:\MyBackups\telemetry_backup.reg"

Restore from Backup

# Restore from default backup location
.\script\off_telemetry_ps7.ps1 -RestoreBackup -BackupPath "path\to\your\backup.reg"

Advanced Usage Examples

# Create backup and continue with telemetry disable
.\script\off_telemetry_ps7.ps1 -CreateBackup

# Restore specific backup file
.\script\off_telemetry_ps7.ps1 -RestoreBackup -BackupPath "C:\Backups\telemetry_backup_20241201_143022.reg"

# Create backup to custom location without running disable
.\script\off_telemetry_ps7.ps1 -CreateBackup -BackupPath "D:\MyBackups\vs_telemetry.reg"

🔧 How It Works

Detection Process

1. PowerShell Version Detection: Launcher automatically detects available PowerShell versions
2. Registry Path Validation: Only existing registry paths are modified
3. Service Management: Safely stops and disables telemetry services
4. Environment Variables: Sets opt-out environment variables
5. File Cleanup: Removes existing telemetry data directories

Registry Modifications

The tool modifies the following registry areas (only if they exist):

• HKLM:\SOFTWARE\Microsoft\VSCommon\*\SQM
• HKLM:\SOFTWARE\Policies\Microsoft\VisualStudio
• HKCU:\Software\Microsoft\VisualStudio
• HKLM:\SOFTWARE\Microsoft\SQMClient

Environment Variables Set

• DOTNET_CLI_TELEMETRY_OPTOUT=1
• NUGET_TELEMETRY_OPTOUT=true
• POWERSHELL_TELEMETRY_OPTOUT=1

⚠️ Important Notes

• Administrator Rights Required: The script must run with administrator privileges
• Backup Recommended: Always create a backup before making changes
• Restart Required: Some changes may require a system restart to take full effect
• Existing Paths Only: The script only modifies existing registry entries
• VS Code Settings: Creates/updates VS Code settings.json with privacy-focused configuration

🔄 Backup & Restore

Creating Backups

# Default backup location (Desktop with timestamp)
.\script\off_telemetry_ps7.ps1 -CreateBackup

# Custom backup location
.\script\off_telemetry_ps7.ps1 -CreateBackup -BackupPath "C:\Backups\my_backup.reg"

Restoring Backups

# Restore from backup
.\script\off_telemetry_ps7.ps1 -RestoreBackup -BackupPath "path\to\backup.reg"

Backup files are standard Windows Registry (.reg) files that can be imported manually if needed.

🆘 Troubleshooting

Common Issues

"This script must be run as Administrator"

• Right-click the batch file and select "Run as administrator"
• Or run PowerShell as administrator and execute the script directly

"PowerShell script not found"

• Ensure the script folder contains the PowerShell files
• Check that file paths are correct

"No compatible PowerShell version found"

• Install PowerShell 7 (recommended) or ensure Windows PowerShell 5.1 is available

Verification

To verify the changes worked:

1. Check environment variables in a new command prompt
2. Look for disabled services in Services.msc
3. Check VS Code settings.json for updated privacy settings
4. Review registry entries (if comfortable with registry editing)
