This tutorial shows you how to boost performance by stopping and disabling unnecessary services on Windows XP Professional systems with Service Pack 2. In the end, 52 services could be disabled; 15 services could be defined to run in "Manual" mode; only 20 services need to be defined to run in "Automatic" mode.

If you followed our Disabling Unnecessary Services tutorial on a Windows XP Professional system with Service Pack 2 installed, you can reduce the running services to a minimum level of 35 essential services need to be running in "Automatic" or "Manual" mode. All other 52 services can be disabled.

With less services running, your system will need less than 190MB of memory to start up. This will greatly boost your system performance.

The suggested minimum set of running services can still allow you to visit Internet and use all local network services.
