function Enable-IEActivationPermission
{
    <#
    .SYNOPSIS
    Grants all users permission to start/launch Internet Explorer.
     
    .DESCRIPTION
    By default, unprivileged users can't launch/start Internet Explorer. This prevents those users from using Internet Explorer to run automated, browser-based tests. This function modifies Windows so that all users can launch Internet Explorer.
     
    You may also need to call Disable-IEEnhancedSecurityConfiguration, so that Internet Explorer is allowed to visit all websites.
