I am seeking a reliable website that lists Windows services and gives guidance as to (a) those services that must not be disabled, no matter what, & (b) those services that can be disabled, no matter what, & (c) those services that might be okay to disable provided that my computer usage meets a specific condition or conditions. Q-1: Do you know of such a website? If so, I will greatly appreciate knowing its URL. Q-2: Your opinion -- How useful is it to disable non-essential Windows services? Or is it just a waste of time to seek out more information on this subject?
