This information is valid for all versions of XP x86 (32-bit) running Service Pack 3. XP Pro x64 (64-bit) Service information and Configurations are also online.
Before adjusting your service settings, ensure that you or your system has already installed all updates by "checking now" for any available updates via Windows Update.
I cannot possibly test all configurations extensively (meaning, each persons specific computer needs), but what I can offer is what "works for me" and the obstacles I have came across so you do not have to discover them on your own. If information on this page needs a revision or expanded, please Contact BV and I will look into your issue.
