System Idle vs Inactivity

Hello,

Would anyone be able to explain the difference between

1. System Idle time, that the Task Scheduler uses
2. Inactivity timer, that the screen saver uses

Thanks
 
System Idle covers the machine's internals.. inactivity timer logs operator
down time..
 
Any chance you can break down the inactivity timer more....for instance I
know that the System Idle monitor the list below, but what does the
inactivity timer exactly monitor

1. There is no user input (keyboard and mouse)
2. The CPU and disk usage is less then 10 percent
3. The system is not running on battery power
4. Presentation programs (such as a Slide show or movie playback) are not
running.
 
You have them backwards.

System idle process and user inactivity have nothing to do with each other.
System idle process is a percentage of the CPU resources that are not being
used by the system. Inactivity, as related to Screensavers and Scheduled
Tasks, is when there is no user input. I.e. keyboard or mouse have not been
used for a period of time by the user.

[[System idle process
The System Idle Process is a process in the Microsoft Windows
operating system that displays, as a percentage, how much CPU resources are
"idle" and available for use at any given time. The name of this "process"
may be a misnomer, however, as the System Idle Process is more of a counter
and less of a process that actually uses the resource percentage that it
displays.]]

[[To run a scheduled task when the computer is idle
1. Open Scheduled Tasks.
2. Right-click the task that you want to run when the computer is idle, and
then click Properties.
3. On the Settings tab, under Idle Time, select the Only start the task if
the computer has been idle for at least check box.
4. Enter the length of time (in minutes) for which the computer must be idle
before the task will run.

A computer is idle when there is no mouse or keyboard activity.
You can specify a length of time (in minutes) in which the computer attempts
to find idle time to run the scheduled task.
You can also specify that any task should be stopped if the computer is in
use by selecting the Stop the task if the computer ceases to be idle check
box. ]]

Take a look at KB article q310601. At the bottom of the first page it
describes The System Idle Task Scheduler service.....

By reading this, I'm assuming that if I create a scheduled task to run after
3 hours of being Idle, and during that time, the CPU usages spikes, maybe
because WSUS has downloaded a patch, that the Idle time clock will reset....

What do you think?

[[A computer is idle when there is no mouse or keyboard activity.]]

User idle time and system idle time are not the same thing.

Your scheduled task has nothing to do with The System Idle Task Scheduler
service.

The System Idle Task Scheduler service schedules SYSTEM maintenance tasks,
the disk layout task, the system restore task and the Help services and data
collection task. The System Idle Task Scheduler service does not run your
scheduled tasks, the Task Scheduler service runs your tasks.

Just like Microsoft to use similar names for different things.

[[Windows XP is designed to automatically perform maintenance tasks to
improve performance and reliability. When your computer is on AC power and
is idle, system maintenance tasks may be able to run for a few minutes.
These system maintenance tasks include disk-layout optimization to improve
performance and preparing automatic system restoration points to increase
reliability. Typically, these tasks occur the first time you leave your
computer idle after you start it. These tasks ensure that the system
maintains its performance and reliability even after long use. Because these
tasks involve reading and writing to the hard disk, the hard disk idle time
is reset regularly during this maintenance period.]]

hmmm,

my problem is that we are setting up a scheduled task to restart machines
after x hours of Idle time. If the machine is in the middle of receiving an
update from SUS, and the xth hour is reached, according to what you are
saying the task will still run, the machine will restart, even though it was
in the process of installing an update.

Is this correct?
Any way around this?
We have our machine setup to check in randomly to our SUS

Also, when created a scheduled task to run when Idle, it says "When the
computer had been idle for".....
it doesn't mention anything regarding user inactivity. After all, the task
should still run when no user is logged on

I honestly do not know from first hand experience if a machine will restart
while receiving an update from SUS. I suspect that it will restart but I
have no way of experimenting.
