After having installed XP SP3 a few times now, I’ve noticed it adds a few new services.

Luckily they are all set to a manual startup, so they don’t seem to impact the system.

The new services are called:

• Wired Autoconfig
• Extensible Authentication Protocol Service
• Health Key and Certificate Management Service
• Network Access Protection Agent

Other than the new services, I’ve not noticed any problems installing SP3
