MORE INFORMATION
LPMTool.exe tool is a command-line application that is used for the following purposes:
 * To collect configuration information about the Lower Provisioning Module (LPM).
 * To upgrade the LPM data or the LPM code.
 * To check the LPM clock.
 * To check the computer usage time balance.

This tool may also be used to troubleshoot issues with computer activation and with adding computer usage time.

The LPM is a component of the Local Provisioning System (LPS) that performs provisioning, metering, and enforcement for prepaid computers and for subscription computers.

File information
LPMTool.exe requires the Pllpm32.dll file to run. The Pllpm32.dll file can be found at the following location:

%windir%\System32

LPMTool.exe parameters
The following table shows the parameters that are supported for the LPMTool.exe tool together with the action that each parameter performs.

These additional messages may appear when you run the LPMTool:  If the LPM Tool does not detect hardware enforcement, a processor-based LPM, or a BIOS-based LPM, the LPM Tool displays the following message:

Software LPM detected.

 If the LPM has not been updated with LPM configuration data and with LPM code, and you use the Windows Preinstallation Environment (Windows PE) LPMToolSuite tool to run the LPM Tool, the LPM tool displays the following message:

LPM not initialized.

Note You will also see this message if the Ppdsubinst.bat command-line tool has not been run during the installation process to configure the computer for a hardware-based LPM platform.

For more information about how to run the Ppdsubinst.bat command-line tool, refer to the Microsoft Windows XP Home Edition for Prepaid Computers and Microsoft Windows XP Home Edition for Subscription Computers addendum to the Microsoft Windows XP OEM Preinstallation Kit.
