You will then have to navigate to the correct entry through the tree on the left hand side of the screen. The path to the entry is: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers\{C822931E-86C5-4482-85C1-049523A13A09}
If an entry for "Log Level" isn't available, create one by right clicking on the "C822931E-86C5-4482-85C1-049523A13A09" registry entry on the left -> New -> String Value and name the entry "Log Level".
After the entry has been created, right click on it, and choose Modify. You will be asked to enter a value here that corresponds to the debug level the Windows Client will use.

3=WARN (only Fatal, Error and Warning)
4=INFO (only Fatal, Error, Warning and Info)
5=DEBUG (only Fatal, Error, Warning, Info, Debug)
6=TRACE (only Fatal, Error, Warning, Info, Debug, Trace)
