    .SYNOPSIS
    Removes one or more Windows app packages based on the target scope.

    .DESCRIPTION
    Iterates over the provided list of app identifiers and removes each one.
    Apps are removed via WinGet (for OneDrive and Microsoft Edge) or via
    Remove-AppxPackage / Remove-ProvisionedAppxPackage (for all other apps).
    The target scope is determined by script-level parameters:
    -Sysprep removes from the OS image for future users; -User targets a
    specific user; otherwise the current user is targeted.

    .PARAMETER appsList
    An array of app package identifiers to remove (e.g. 'Microsoft.BingNews').

    .EXAMPLE
    RemoveApps @('Microsoft.BingNews', 'Microsoft.BingWeather')

    .EXAMPLE
    RemoveApps -appsList (GenerateAppsList)
