    Does the Data Execution Prevention feature of Windows XP give a warning message if
    it has closed an application?

    I have recently turned on DEP for all programs, and after that, some of my programs
    (Counter Strike: Condition Zero, Riva FLV Player and a few other programs) don't run
    anymore. Opening them gives no prompt or error message - they just don't run. I have
    tried setting DEP for Windows Programs and services only and they work fine if this
    is the setting I choose. My processor (Intel Celeron M) supports hardware-based DEP
    protection.

    I have now included Condition Zero's executable in the DEP exclusion list.

    I am wondering if I have changed a setting somewhere as I don't get any prompts/warnings at all. Some programs just don't run after enabling DEP for all programs.

    I notice that my system running windows 2003 does the same thing, by default it automatically shuts down apps with no warning. There must be a setting for it somewhere unfortunately i have no idea where.

    Usually it is your AV that is the problem. Get a different AV if you cannot use DEP. There is little point in using DEP if you have to exclude anything.
