Before Continuing: Please be aware that changes to the Windows Registry are made in upcoming steps. Take great care in making only the changes described. I recommend that you backup the registry keys you're modifying in these steps as an extra precaution.
First, locate the HKEY_LOCAL_MACHINE folder under My Computer and click on the (+) sign next the folder name to expand the folder.
Continue to expand folders until you reach the HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\Current Version\WPAEvents registry key.
Click on the WPAEvents folder once.
