Windows 7: Question about MSE

Most times when MSE somehow senses that an update is available, it turns yellow. Of course it also does when it needs to do a scan. open it up and it will tell you that it needs to update..

I have mine set to "check for updates but let me choose whether to download or install them" and MSE updates itself without me doing anything.

I have MSE set up to check for definition updates every 4 hours in Task Scheduler. My Windows Update is set to notify me when updates are available.

The CPU usage can be throttled to as low as 10%. Is MSE not honoring that for you?


I too tried that registry change - but that was so long ago that I do not recall the results. My guess is that it did not work or I would have stuck with it instead of using this command line/batch file/scheduled task:

"C:\Program Files\Microsoft Security Client\Antimalware\MpCmdRun.exe" -SignatureUpdate

But MS only updates the sig file once per day in most cases. If you do not wish to have the cmd prompt window popup each time, then there are ways around that. I had the scheduled task set to run every hour while I was fighting repeated failures to update... it did not help.

It is my understanding that MSE uses the same backup files/system/scheme as used by windows update. You just happen to see some of the updates via the WU interface because the timing of the sig file release, the timing of the OS update checks and the timing of MSE's update checks.

I've not been able to test on W7 as extensively as I have on XP, but MSE's update process will often fail if the OS temp directory has been moved to another folder via OS environment variables. You can watch MSE put temp files into the correct/defined OS temp folder and then at the very end of the update process, it is hard coded to put stuff into the %SystemRoot%\temp folder. It honors %SystemRoot%, but does not all look at where the OS temp file is set to for all things. Sadly, this has been discussed in MS forums for years without a fix by MS. I fought this for more than a year - spending hours with MS support and remote control sessions where agents followed the same useless scripted "fixes". The end result for all 3 of those tickets was "we don't know what is wrong". I eventually stumbled upon the fix in an MS forum post. My subsequent contact with MS has not yielded any change to their update process code.

The "fix" is to leave a temp folder in the system root folder since the update process does not always recreate it.

MSE does have a good implementation of its LSP - thus it gets along with other software that use LSPs (imaging software, backup software...) And MSE is easy on the system resources - even if its heuristics suck and MS is slow to add things to the sig list. I base that claim on my numerous submissions to both MSE and virustotal after cleaning computers that were "protected" by MSE. I keep checking virustotal until MSE added the item of interest - usually in a day or two.

MSE has a EULA that is friendly towards the non-profits for whom I do volunteer computer support. AVG, AVAST & others; not so much.

MS updates definitions 2-3 times per day, usually 3.

Thanks for correcting that. I can only suppose that I was not seeing this due to the number of failures I was getting on computers that I had set to update every hour. I was lucky to get one success per date - so I drew the wrong conclusion.

I have MSE set to check for definition updates before running a scan and I have a Quick Scan scheduled for every day. That way I'm sure to get updated definitions every day. That was the simplest way for me. Otherwise MSE as has been said kind of runs on a weird schedule in terms of definition updates.

Cool.
For what it's worth I've set up scheduled tasks on many PC's and have never really had problems.
Just lucky i guess
In WU History i do see a few Failed updates per year...not enough for me to bother with it.
I never saw 2 failed updates back to back.

MpCmdRun does write to several logs.
If you haven't looked at C:\Windows\WindowsUpdate.log, check that for "MpCmdRun".
There may be some detail info in there for problems with this.

I've never setup a schedule to check every hour, but i don't see how every 1 hour versus every 3-4 hours would matter.
I can change a pc to check every hour if you want?...

Also, I found this task must run with Admin authority.
From what I remember it will run with STD authority, but does not update the definitions.
I can't remember if any error is reported running under STD auth.

regards, David

That's how I first used it.
But i got tired of seeing the "Updates Available" icon.
I also wanted these updates applied more than once per day without me doing anything (lazy)...
I do still use scheduled daily scans, but added the scheduled task for the updates.
