Enable Verbose Global Policy Logging

Having problems with login scripts and Group Policies? You can enable verbose logging to track all changes and settings applied using Group Policy and its extension to the local computer and to users who log on to the computer. The log file, userenv.log, will be written into the %windir%\debug folder. This folder is a hidden folder. To enable verbose logging (Userenv.log):

Hive: HKEY_LOCAL_MACHINE
Key: Software\Microsoft\Windows NT\Current Version\Winlogon
Name: UserenvDebugLevel
Type: REG_DWORD
Set UserenvDebugLevel=30002 is for verbose logging, UserenvDebugLevel=30001 is for errors and warnings only, and UserenvDebugLevel=30000 logs nothing.

This hack provides very detailed information above and beyond what can be determined by running the Global Policy Results utility.
