XP is starting Windows time long or stuck how to do

Do not know when, home computer (Xp SP3), each time you start, in the "Windows are starting" waiting screen, each time to wait for a 45 seconds or so. The following figure:

Check the boot start item, and did not find anything unusual, should be the system services out of the problem, and finally found that the event Log service startup method is manual, I do not know when to change it to manual.

Change this event log service to Automatic and reboot OK.

Specific location: Control Panel-management tools-Component Services

There are three directories below the console root directory, service (local) find inside

Why does event log without starting cause slow startup? Prefetch (pre-access) requires this service, and the files under C:windowsprefetch depend on this service for recording.
