- Open regedit and go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion
- Create a subkey named "Diagnostics"
- Create a new DWORD value under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Diagnostics named "GPSvcDebugLevel" (this is case sensitive)
- Set the value of GPSvcDebugLevel to 0x00030002
- Create the "usermode" directory under %windir%\debug\

- Your new log is at %windir%\debug\usermode\Gpsvc.log
