CTFMon.exe
(Microsoft)
CTFMon comes with Microsoft Office XP and Windows XP it activates the Alternative User Input Text Input Processor (TIP) and the Microsoft Office XP Language Bar. As long as the Text Services & Speech are enabled in the Control Panel, this program will force itself back into your list of background programs.
Recommendation :
Disable "Text Services & Speech" in the Control Panel if you are not using them. Then, disable CTFMon using Startup Manager. (Note that if you use Word, Excel or PowerPoint to write in different languages, eg. English and Arabic, then you will be using "Text Services & Speech" facilities).
