I needed to modify tens of existing shortcuts to run referenced applications in elevated mode. It is possible to do it in properties of the shortcut (Advanced - [x] Run as administrator) but I prefer PowerShell (actually .NET Framework) to do bulk operations. I wrote this function for you.

Function Set-RvShortcutToRunAsAdministrator
{
    <#
	.SYNOPSIS
        Modify existing shortcuts (links) to run application in elevated mode (Run as administrator).
