Question: What is the difference between clicking APPLY or OK in a control panel?
The IT Guy says:
Clicking "apply" makes whatever changed settings you selected in a system control panel go into effect without closing the control panel window. This is convenient if you are not sure if the settings you have selected are the ones you want to keep. If you click APPLY and don't like your selection, you can immediately change the settings to something else without again going to START, choosing SETTINGS, and then CONTROL PANELS.
Clicking OK essentially does two things: it applies the settings you selected (just like clicking the APPLY button would) but it also closes the open control panel window.
