How to know which programs are running on my computer?

Question

Double mbs are being consumed as compared to before when i use the msgr, i think something is running but not visible, how to remove it.

Answer 1

Windows:

For running processes Press Ctrl+Alt+Delete and see the memory usage.

To stop processes from automatically starting up, Go to start>Run, type msconfig, hit enter. On the startup tab uncheck any useless process. Don't uncheck the critical processes though.

GNU/Linux:

Run 'top' or ps -e

Mac:

Mac sucks. But I think the same commands will work here too.

Answer 2

Why oh why doesn't anyone ever mention what operating system they're using?

What is it: XP, Vista, a Mac (no Linux user would ask this question)?

If XP, right-click the taskbar & select Task Manager.  Or do an internet search for 'Autoruns' and install it (it's free).
