CTFMon is involved with the language/alternative input services in Office XP. Ctfmon.exe will continue to put itself back into MSConfig when you run the Office XP apps as long as the Text Services and Speech applets in the Control Panel are enabled. Not required if you don't need these features. For more info on ctfmon see _here_. Ctfmon can be disabled from Control Panel, Text & Speech Services. Note - the file will always be located in the System32 folder, if it is located elsewhere it will likely be a worm or trojan! Can cause problems with some other programs if left enabled - see _here_ for such an example
