I found this previous post:
No. The explorer refered to in the Close Program box is the task bar explorer. When you End Task it closes the task bar but re-opens it a few seconds later. This ends up closing the program boxes you had open on the task bar. A fast way to close everything.
I'm a bit confused as to whether I should end task of explorer and sys tray after reading the previous post and reading the above post from a previous topic?
Maybe I did not express myself clearly enough, all I wish to know is whether it is safe to:
end task of explorer and sys tray in the close program box
as some web sites say yes and some say no!!!!!!!
