Windows 10: High CPU usage by IE 11

For the last couple of weeks IE 11 is constantly using about 10% of my CPU power all the time. I've run several different security checks and they all come up without any issues. I've disabled all add

Excessive CPU usage by IE 11

For the last couple of weeks IE 11 on my Windows 10x64 PC has been using an excessively high amount of CPU constantly. 1 or 2 tabs never trapped CPU usage below about 7% even after webpages that open for a significant amount of time. I've run all the tests
I can think of including SFC/scannow which reported no problems.

Obviously this is affecting everything I do on the PC while I have IE open.

 

Windows 10 Calendar App will not show any events older than a month....help!

I am getting the same run around on IE 11 CPU usage. Months and no fix.

 

Hi MSRadell.

Have you tried resetting IE?

Edit 1:

How many home / start pages are you using? Have you tried with none?

 

Yes, I’ve tried resetting IE, I’ve actually done it several times. I only have one homepage set (CNN.com) and I’ve already tried removing it. I’m not quite sure when it started but it’s within the last couple of weeks.

 

Might I suggest Process Explorer as part of Sysinternals. It might give you more insight.

See if the Internet Explorer troubleshooter from the Microsoft easy fix changes the performance:

https://support.microsoft.com/en-us/...-fix-solutions

 

I use that utility all the time. Here’s a screen capture showing what Internet Explorer is doing:

 

I tried the link provided and downloaded the file for diagnosing Internet Explorer performance. However it won’t run and it says that another file that’s required is missing.

 

So no real information from Process Explorer.

Can I ask what security checks you've run? Have any installed themselves into IE?

In a previous post you said you disabled addins, have you removed them?

 

As far as security goes I have Norton Security installed on the machine and I have run Malwarebytes when I discovered the problem. Neither 1 of them or picking up any issues.

 

How about another browser. I started Chrome and its usage hung around 3%-5%. After about 10 minutes it sunk to zero and would then pop to less than 2% and back to zero.

With Malwarebytes are you scanning for rootkits.

 

It doesn't happen in Google Chrome or Firefox.

Yes I ran the Rootkit portion of Malwarebytes as well as the normal scan and neither found anything questionable.

 

Back in post 7 of this thread when you went to run the trouble shooter you said a file was missing.

Long shot but maybe this usage is tied to that missing file.

Did it record what file was missing?

When you start IE have you reviewed Event viewer to see if any items are being logged.

Have you run sfc /scannow ?

The file that was missing was one required to run the troubleshooter, not one that was part of IE I don't know of any missing file as part of IE.

Event viewer didn't show anything unusual but I look at reliability history I did find a couple of different events, I've attached a screenshot of 1 of them.

I've run SFC/scannow it came up clean with no problems found.
