The default value in the absence of an entry is 86,400 seconds; equivalent to a day's time (24 hours). To reduce the storing time, create the entry then enter your preferred time in seconds.WARNING: This requires going into the Windows Registry, thus should be done only by those know how to restore their Registry.
