DisableLogMeInPatchManagement.ps1

<#
.SYNOPSIS
    Ensures proper configuration of targeted Registry Key Property Values to prevent the LogMeIn Patch Management feature from interfering with the Windows Update subsystem.
.DESCRIPTION
    There is a limitation on the WUAUSERV application that makes it a single user application.  During the Patch Cycle of LabTech, if another application (LogMeIn) tries to invoke a call to it,
    It will cause the LabTech Patch Cycle to fail.  This registry configuration will prevent the LogMeIn service from using the Windows Update subsystem.
.INPUTS
    None.
.OUTPUTS
    None.
