Potential Conflicts with the Global Logger Session

Published: June 11, 2010

Updated: June 11, 2010

Applies To: Windows 7, Windows Vista

The Update Compatibility Evaluator (UCE) uses the Global Logger session to trace registry, file, and module load activity occurring early in the operating system boot process. The registry values configured for the Global Logger session also affect any provider that logs an event to the Global Logger session. Applications or drivers that use the Global Logger session must reconfigure the Global Logger session registry values after uninstalling the UCE.

The UCE sets the values to the registry key, as shown in the following table.

 

Registry Key Value

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\WMI\GlobalLogger\Start

1

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\BufferSize

256

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\MinimumBuffers

25

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\MaximumBuffers

400

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\MaximumFileSize

Credits available to write on the scratchpad directory.

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\FileName

<UCE_scratchpad_directory>\Boot.etl

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\FlushTimer

60

HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\AgeLimit

5

After you uninstall the UCE, the HKEY_LOCAL_MACHINE \System\CurrentControlSet\Control\WMI\GlobalLogger\Start registry key value will be 0.
