    scheduled tasks that collect or report telemetry data on Windows.

    .EXAMPLE
    Get-TelemetryScheduledTasks
#>
function Get-TelemetryScheduledTasks {
    return @(
        @{ Path = "\Microsoft\Windows\Application Experience\"; Name = "Microsoft Compatibility Appraiser" },
        @{ Path = "\Microsoft\Windows\Application Experience\"; Name = "Microsoft Compatibility Appraiser Exp" },
        @{ Path = "\Microsoft\Windows\Application Experience\"; Name = "ProgramDataUpdater" },
        @{ Path = "\Microsoft\Windows\Application Experience\"; Name = "StartupAppTask" },

<#
    .SYNOPSIS
    Disables known Windows telemetry-related scheduled tasks.

    .DESCRIPTION
    Iterates over a predefined list of Windows scheduled tasks associated with
    telemetry and disables each one that exists and is not already disabled.
    Supports -WhatIf to preview changes without applying them.
