After finding out that Service Pack 2 for Windows XP will not be released until sometime next year, I thought that I would update the Windows XP Services Information.
This update expands the dependencies of all the services to include not only what a particular service needs to run, but what other services require it to be functional. This could reduce the headache of attempting to cross reference services and may assist you in determining what services you can safely disable on your system.
Unfortunately, the printable PDF version is not finished. I spent over 3.5 hours on getting what information I did update posted. I will try and format it tomorrow.
