    .SYNOPSIS
    Function for forcing redeploy of selected Win32App deployed from Intune.
 
    .DESCRIPTION
    Function for forcing redeploy of selected Win32App deployed from Intune.
 
    OutGridView is used to output found Apps.
 
    Redeploy means that corresponding registry keys will be deleted from registry and service IntuneManagementExtension will be restarted.
 
    .PARAMETER Online
    Switch for getting Apps and User names from Intune, so locally used IDs can be translated to them.
 
    .PARAMETER excludeSystemApp
    Switch for excluding Apps targeted to SYSTEM.
 
    .EXAMPLE
    Invoke-IntuneWin32AppRedeploy
 
    Get and show Win32App(s) deployed from Intune to this computer. Selected ones will be then redeployed.
 
    .EXAMPLE
    Invoke-IntuneWin32AppRedeploy -Online
 
    Get and show Win32App(s) deployed from Intune with friendly names. Selected ones will be then redeployed.
