>> How can I best maintain my XP Professional? <<

No one can assure that if you follow some procedures your windows XP won't be broken. Reviving it it's more difficult than in legacy windows versions.

Anyway, although your 1 line question is so vague, I'd give four lines answer. Run disk cleanup, defrag. Test your PC for viruses and spyware. Have a firewall as a minimum line of hacking defense. Download and install from windows updates the security patches. These are very basic advises.

Good Luck,
