This question already has an answer here:
I have Windows XP Profesional here and it gets very annoying when an application that I launched five minutes ago finally brings up its main window and steals focus from the email that I'm writing (or other currently focused window). Is there any way, native to Windows XP, that I can disable this? I know some applications will just blink their title bar on the Taskbar rather than stealing focus, but they don't all behave this nicely.
I am working in a corporate environment, so there may be a limit on what extras/tools can be installed. Also, I am not sure I have access to regedit (and even if I do, Helpdesk will probably not be amused if they find I'm using it).
