Services You Can Disable, XP users

There are quite a few services you can disable from starting automatically.
This would be to speed up your boot time and free resources.
They are only suggestions so I suggestion you read the description of each one when you run Services
and that you turn them off one at a time.

Some possibilities are:
Alerter - Sends alert messages to specified users that are connected to the server computer.

Application Management - Allows software to tap directly into the Add/Remove Programs feature via the Windows Installer technology.

IP SEC - Manages IP security policy and starts the ISAKMP/Oakley (IKE) and the IP security driver. If you are not on a domain, you likely don't need this running.

Messenger - Transmits net send and Alerter service messages between clients and servers. This is how a lot of pop-up windows start appearing on your desktop.
