Visual-Studio-Telemetry-Disable-Tool/script/off_telemetry_ps5.ps1

<#
.SYNOPSIS
    Improved comprehensive script to disable telemetry in Microsoft development tools
.DESCRIPTION
    This script safely disables telemetry, crash reporting, and data collection for:
    - Visual Studio 2015-2022 (only if installed)
    - Visual Studio Code (only if installed)
    - .NET CLI
    - NuGet
    - Various Visual Studio services
.NOTES
    Must be run as Administrator
    Improved safety - only modifies existing registry paths
    Compatible with PowerShell 5.x
    Includes comprehensive backup and restore functionality
.PARAMETER CreateBackup
    Creates registry backup before making changes
.PARAMETER RestoreBackup
    Restores registry from backup file
.PARAMETER BackupPath
    Path for backup file (default: Desktop)
.EXAMPLE
    .\off_telemetry_ps5.ps1 -CreateBackup
    .\off_telemetry_ps5.ps1 -RestoreBackup -BackupPath "C:\Backup\registry_backup.reg"
