Windows 7: CPU usage in idle

Milesahead,
Indexing is much improved in win 7. One can always:
Control Panel | Indexing
and then select what one would like indexed.

You can also use the cpu tab of RESMON.EXe to see which processes are using what.

Guys Thank you very much on all yours replies. It makes sense and to be honest some of your suggestion I did even knows that they exist.
I will definitely try and see what I will get but I would like to say that I have made some changes with Services.
When you go in Task Manager on TAB Services and then you on the bottom right press Services… again you got two tabs Extended and Standard.
I went through Extended… tab and after careful examination of all that are started automatically or with delay I have Stop and disable or set on Manual. I did make change only on processes that I definitely know that I don’t want them up and running. Such as, Acer updates, Acers other services etc. After that it came with significant difference. But I have to emphasise I still didn’t have enough time to check if this is working now for good or not.

As anti-virus I use Microsoft security essential and F-Prot. Both they are up and running. I know that might be a problem. If you think so please advise me what I should do/change.

Stop messing around with the services. Let well enough alone. Solve problems instead of creating them.

Remove 100% f-Prot.

I prefer to use Everything Search. The behavior doesn't change just because you have Windows 6.1 instead of 6.0. The monitoring is much more intelligent than the indexing service. It doesn't launch dozens of svchost processes to read every file on my drive. I'd rather just use a tool that works out of the box than spend months tuning one that will never work the way I want.

Seriously...what is the problem? Why do you not want the computer to do work while you are not using it? Would you prefer it tried to do work while you are using it? Come on, what problem is it causing having idle computer usage?

@Karl:

I just wanted to follow up.

Before I went ahead and did SFC Scan now, just for kicks I ran a full scan, and viola!!! the scheduled MpIdle task scan disappeared!!! No more CPU usage by MsMpEng.exe at idle. Issue gone.



Here is what I THINK MSE was trying to do.........

I believe that when the new MSE Client version 2 is installed as a precaution it wants to do a full deep scan of the PC just to be sure that everything is clean. Since by default MSE is only set to do a "quick scan" on a schedule.

MSE tries to be less intrusive by doing the full scan over a long period of time by way of the MpIdleTask scan. But some of us are very observant notice the HDD activity and until we look further believe that something is amiss. But it isn't.

The reason I think this is because in another thread here someone indicated that they found the same "issue" and it was resolved with a manual full scan. So it appears to be the design architecture trait. Of course having a very old CPU doesn't help I'm sure as most users have at least a dual core now.

Here is a link to the other thread about this:


Pretty interesting read as well.
MSE thrashing disks after boot.

legacy,
basically you are correct. I forgot that most are not aware that when ms also did an engine update they scheduled a full scan to make sure that all known malware, not just viruses, was removed.

consequently, during idle times, mse is working away.

I also after the engine update, immediately ran a manual full scan.

The problem lies with the definition of "idle." Since CPU usage is easy to detect and HD usage not so easy, low CPU usage for a period of time usually is all that's needed to constitute the "idle" condition. When I bought my first Vista machine, unknown to me, defrag.exe was in the task scheduler. Having just removed a bunch of crap ware I thought I'd run a defrag using jkDefrag(as it was known at the time.) Well what a surprise I got when the system decided it was "idle" while I was in the middle of a defrag and ran defrag.exe.

Needless to say, stuff crashed.

The WinAPI needs an Idle function call that takes disk usage into account. Especially if it's the system disk. The WMI performance scripting mumbo jumbo is just too arcane.

@karl:

I think the only problem I have is using an ancient P4 1.5Ghz processor. LOL I can't get upset and don't with MS because they can't possibly take into account such an old "legacy" piece of hardware! LOL

@MilesAhead:

Yes, but normally for MSE anyhow most people are at least using a 5 y/o or less CPU so what kills single core stuff that is old probably doesn't make much impact on a something made from say 2006 on.

I know you gurus here probably get annoyed at some of us "amateur" users especially when we come begging for help and then we don't always follow your directions correctly, so we have no one to blame but ourselves, but I appreciate help I have received here from you all. !!!!!


I absolutely LOVE this site , and find Win OS's fascinating and I'm endlessly interested in anything PC hardware or software. I just don't use a computer I like to understand how they work too. But I know that MS has to make sure that the everyday user is well taken care of only a few of us are really geeky in this respect.

I can't imagine what it would be like using Apple OS X. How boring! Seriously! If I had to look at a different OS I guess it would be Ubuntu. Oh well, Apple is too cool for me anyhow.

Since I still have one PC operating on XP does anyone have a suggestion as to which site would be on par with sevenforums ?
