Task scheduler

[Bebeoix]

Hello,

Why Seven is the first Microsoft OS with 35 active tasks at the beginning ?

We can disabled tasks scheduler ? Or delete this 35 tasks ?

Seriously i am note sure if in the 35 tasks they are important for the system ?
I'm the first who have discovery that or ... ?

Thanks.
(sorry for my English)

Task Scheduler starts and stops tasks constantly. These tasks arent always running. Some will trigger durring logon and stop after the task is completed.

When a task is listed as Active it dosent mean thats its currently running. Only that the task is set to run if a condition is met. You can see this in the Trigger column and Last Run column.

Double click the task. If the status is 'Ready' then it is not running.

I have 38 active tasks with only 1 task running. The other 37 are at idle waiting for a trigger so they can run. After they run, they will stop and return to the idle state.

Thank you, but i know that.

All tasks is idle for the moment, but when the trigger is set (00:00 H, or 01:00 H, etc...) the tasks launch.

My question is not how a tasks is launched.
My question is why with windows Seven, we have ~35 tasks in the tasks scheduler ? It is necessary for the OS ?

Thanks.

Do not touch those tasks; Windows 7 uses the Task Scheduler to launch system and maintenance tasks in optimal circumstances for you and your system.

This way they don't need to run all the time.

Again: DO NOT touch them, once they are deleted, I'm not aware of any other way to reinstate them other than a repair install or reinstall.


(Ever since I installed Windows 7 in August and looked around a bit, I was afraid of this day, when a noob will discover it and have that irresistable n00bish urge to delete it all 'cause 'it seems two much'.)

I have disabled the task scheduler.
It is only for Microsoft experience program. Not important for the system.

 

[Teerex]

No, it is not only for that.

But, you, you do whatever pleases you, you're the smartest guy.

Just don't come back here crying 'I broke something, fix it, now!', OK?

Hello... I have been disabling individual tasks (and triggers) for a long time. Since XP days. I am a PC gamer and like to run "lite." I go thru "services" also, disabling what I can that I think I do not need. But I do not turn off Task Scheduler in Services. That stays running.

Now on 7 Pro I have like 31 processes running, better than Vista's 38 or 39. I like blackviper.com to aid in what services I want to turn off.

I do not notice and have not noticed any adverse affects by do what I do. So I will stick to it. System runs lean and games run great.

Cheers,

My recommendation would be to at least remember what services you are disabling, preferably by quickly documenting it, so that you can undo those changes in the future should a problem arise.

I have been burned twice over the years by disabling services as per blackviper, but then only to discover at some future point that an OS or network problem with which I had been struggling was ultimately related to a service being disabled. Good way to learn lessons but at the cost of time and some frustration.

Unless you the user knows exactly what a particular service is for (educate yourself on what all the services do) and are not relying on some guys website ( went to that site BTW, would not recommend his advice), then feel free to turn off services that are not needed for your particular setup.

If YOU don't know what a service does then don't disable it because someone said its okay.

That may have been required for Windows XP. But it is pointless and not required for Windows Vista or Windows 7. Windows built-in services or tasks do not in anyway effect performance. Third-party applications and services effect performance.

There are numerous tasks that start and stop and I haev yet to realize any bennefit from disabling either the task service or individual tasks.

If you display RSS feeds via desktop gadget (or in IE). They would no longer update.

Scheduled scans for MSSE or Defender would no longer run. Windows Backup, Defrag are a couple more scheduled utilities that run in the background. Offline files, System Restore (VSS) the list goes on.

Even the reliability monitor has a scheduled task to update and collect information for the report/graph.

But the great thing? At no given moment are all of these running at the same time. They individualy start, complete the task and stop.

Yes, of course. Great advice. We all learn the ins and outs over time. I think frustration comes from so many things, not just turning a service on or off.

I only use blackviper as a guide, not as gospel. I do know what each process is for, I do not turn them off for the sake of it. I only turn off what I will not need or use. Been at this a very long time, building my own (and others) systems for years. When you know, you know.

Is there any documentation on this? I want to take your advice, but just saying so does not make it so.

Windows Internals 5th Edition, page 598, I/O Prioritization.
Windows Internals 5th Edition, page 809, Page (Memory) Priority.

Or you can read these here:
Windows Administration: Inside the Windows Vista Kernel: Part 1
Windows Administration: Inside the Windows Vista Kernel: Part 2

Every background task Windows runs does so in a low priority.

Thank you, I am not so stuck to say I can always learn more. Information is knowledge.

even disabling few services i don't think it is not going to help much with performance. i'd say keep the services running as it is but you can disable the ones you know for sure is not a system service.
