As part of a troubleshooting request we may ask for an export of a specific Windows registry branch.
In this case you can invoke Regedit from within a Windows command prompt and use the Export function:
In this example we have requested a dump of the registry branch 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Wisp\Pen\Digimon'
The export request will create the file digimon.reg. You may need to send this to a .zip file as many email systems will block .reg attachments.
