Registry Trees for Devices and Drivers

The following trees in the registry are of particular interest to driver writers (where HKLM represents HKEY_LOCAL_MACHINE):

• HKLM\SYSTEM\CurrentControlSet\Services Registry Tree

• HKLM\SYSTEM\CurrentControlSet\Control Registry Tree

• HKLM\SYSTEM\CurrentControlSet\Enum Registry Tree

• HKLM\SYSTEM\CurrentControlSet\HardwareProfiles Registry Tree
