  1. Overview of This Release
  ======================================================================
     This patch updates the AcAgent program to ensure that the
     AcAgent Notification Window can start successfully without
     causing a high CPU load and that the AcAgent Service program 
     doesn't further increase the CPU load when running in the process 
     monitoring mode.


     1.1 Resolved Known Issues
     ===================================================================
     This patch resolves the following issue:

     Issue 1:    CPU usage may surge on an agent endpoint when the
                 notification window is opened by right-clicking "About"
                 or "Log" from the system tray.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 1: Apply this patch which contains the updated 
                 "AcAgentUI.exe" and "AcAgentUINotifiy.exe" files.

     Issue 2:    CPU usage may surge on an agent endpoint when 
                 the agent encounters difficulty collecting user process
                 information.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 2: Apply this patch which contains the updated 
                 "AcAgentService.exe" file.
				 
     Issue 3:    The agent "acdriver.sys" may not execute on Windows XP
                 Embedded systems because the file name may be converted
                 to upper case and become unidentifiable to the Endpoint
                 Application Control agent.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 3: Apply this patch which contains the updated 
                 "acdriver.sys" and "acdriverhelper.sys" files.

     Issue 4:    Endpoint Application Control is unable to 
                 distinguish agents that are installed on duplicated
                 Windows systems where the universally unique 
                 identifier (UUID) remained unchanged after the
                 duplication.

                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 4: Apply this patch which conatins the updated installer
                 "AcAgentSetup_x64" and "AcAgentSetup_x86", available in
                 both the exe and msi format, and modify the endpoint
                 UUID value using the command-line interface. For 
                 details, see sections 4.2 in this readme.

             line. Note that it runs in silent mode.

             i. 64-bit:

                msiexec /i AcAgentSetup_x64.msi REINSTALL="ALL" 
                 REINSTALLMODE="vomus" ServerHost=serverIP:port or
