What is an autologger?
An autologger is a trace session that records events from user-mode and kernel-mode trace providers during the boot process. This feature lets you trace the actions of a trace provider while Windows is booting.
Autologger sessions are supported only on Windows Vista and later versions of Windows. On these systems, you can log to a Global Logger trace session, as described in Tracing During Boot, but autologgers are the preferred method.
For more information about autologgers and methods of boot tracing in prior versions of Windows, see Tracing During Boot.
