Microsoft Security Essentials and Windows Defender performance tweak

I just found this tip and thought I'd pass it along:
Fix High CPU Usage & Perfomance of Microsoft Security Essentials and Windows Defender

That is rather interesting, indeed. If that is the case, then I would have to say that Microsoft has created their own flaw there as far as performance goes.

 

MS still has not fixed this? I believe it has been an issue for years.

 

This tweak is several years old, i have done that more then 3 years ago!

 

And where does it say that it's still necessary to apply this tweak?

 

I've never seen such high cpu usage under Windows 8.1 & 10.

 

Good for you, the reason why I replaced WD on 10 was just because of this. Several other people mentioned it over the time as well.

 

A few months ago I installed MSE on Windows XP because of comments on here about how "light" MSE supposedly is. The impact on the system was so noticeable that I immediately uninstalled it. I am tempted to reinstall MSE to see if this tweak makes any difference.

It's clear now that MSE & WD are the target to shoot at on every thread created for them

Is it really necessary to create a new Windows Defender thread every week?

 

@Macstorm : I know exactly what you mean.

In real life, stalkers are prosecuted and sentenced.

And compulsive behavior are treated.

In tech forums however, it's apparently considered to be a cute hobby.

I'm unable to understand why any individual dedicates their life to spreading bile.

Life should be lived with a smile instead.
So here is one from me :

 

I agree 100%.

We should all respect one another's opinions.

By the way, I have appreciated, benefited, and learned from many of your posts. So I thank you for that.

 

Thank you very much, @WildByDesign.

You are one of the users here, who I always enjoy reading posts from.
Your always helpful posts in every thread you show up in, are a perfect example of how forums ought to run.
I have a lot of respect for that.

 

@Martin_C Thank you, Martin. That made my day, without a doubt. I don't always have the same deep level of technical knowledge as many of the other helpful members here, but one thing that is for sure is that I will always be happy to give some of the time that I do have available to help other members on subjects that I am able to help with. The reality is, I had learned so much here at Wilders even back as far as 10+ years when I did not have an account at the time. So now is my time to pay pack what was provided to me earlier on. It's the community aspect which I enjoy and appreciate most about forums such as Wilders.

 

I did have a bit of a problem with memory and CPU usage with MSE version 4.8.204 upon install but it subsided after a few days after I used the OP's suggested fix. However, with the current version 4.9.218.0, have no problems with CPU or memory WITHOUT the afore mentioned fix. Well satisfied. P.S. I do use my seatbelts and airbags activated while driving.
