Extremely slow IE11 under windows 10

This is no way endemic to Windows 10. I have Edge and do not use it. I use IE 11 exclusively and there is no issue with. I do this with 3 Windows 10 machines.

1. Run SFC /SCANNOW from an Admin Command Prompt.
2. If you still have issues, uninstall (remove) the Network Card (s), shut down, start up and let the network cards reinstall themselves.

Then run TCP/IP Reset

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

If you have continued issues, you may need to reinstall Windows 10 from the Media Creation Link and Keep Everything.

Open a command prompt windows, type the following and hit Enter, to open IE in No add-ons mode:

 “%ProgramFiles%\Internet Explorer\iexplore.exe” -extoff

Will still IE 11 freeze?

To hopeleonie:

Your solution does provide a significant improvement in ie 11 response time. That is the good news. The bad news is that such improvement comes at the cost of functionality, particularly from Norton add-ons.

To John Hurst:

Thank you for the suggestions. Results are as follows;
1. SFC /SCANNOW ran without error.
2. Remove the network cards and restart: no effect.
3. Netsh command failed with the below errors:

   C:\WINDOWS\system32>netsh int ip reset c:\resetlog.txt
   Resetting Interface, OK!
   Resetting Unicast Address, OK!
   Resetting Neighbor, OK!
   Resetting Path, OK!
   Resetting , failed.
   Access is denied.

    Resetting , OK!
    Restart the computer to complete this action.
   
    Please note the "Access is denied" in spite of the fact that the command was run as Administrator
4. ipconfig flushdns ran successfully
5. net stop dnscache ran successfully
6. net start dnscache reported "The requested service has already been started"

I will now restart my computer, retest and let you know the result(s)

I also tried the following:
1. Disabled the Wifi network adapter (Qualcomm Atheros)
2. Reset the Ethernet advanced Speed and Duplex value from Auto Negotiation to 100 Mbps Half Duplex. This successfully prevented the network icon at the bottom of the screen from flashing ON and OFF every 30 seconds or so. That, however, did not prevent internet explorer from freezing on and off every 30 seconds as before.

Any  suggestions?

I suggested above a repair using the Media Creation Link and suggest that is what you now should consider

Go to the Media Creation Link

https://www.microsoft.com/en-us/software-download/windows10

Click on Upgrade to Windows 10 (even if Windows 10 is running), click on the Download button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

To: John Hurst:

I just completed the series of steps you recommended (https://www.microsoft.com/en-us/software-download/windows10) and the results are inconclusive. Essentially, there seem to be occasional flashes of speed (switching from one web page to another, at other times, internet explorer freezes as much as before.

Incidentally, my old OS build was 10586, now updated to 14393. Version number is 1607.

I am going to use my PC for a couple days to see whether its behavior changes and will let you know.

After several more hours of use, Internet Explorer keeps on freezing as before.  Boy, do I miss XP !!

Thank you John. My PC is less than 2 years old and should not have any problems running Windows 10.

I have taken note of your suggestion and may apply it at a later date when my schedule is not as full as it is now.

Again thank you for your help.

Thanks for the update. Given your posts and issues, you should back it up and do a completely fresh install.

I have spent a tremendous amount of time trying to resolve this issue and cannot continue investing more time. I am putting this issue on hold and will take it up again when time permits. Thank you John and Hopeleonie for your assistance.

I am now closing this case.

Follow up alternate solution.

I finally resolved the problem by simply switching to Google Chrome. Response time is now back to acceptable intervals as the browser responds within a second or two. I was able to use the Norton Toolbar which I find useful. The absence of a menu is really not a problem since the menu function is now available through the 3 stacked dots at the top right side of the display.

The feeling is one of having been stuck in stop and go traffic for hours  and eventually being able to return to freeway speed.

Goodbye Internet Explorer !

If IE will not run on your computer, there is something wrong with the operating system, or possibly the hardware is not fully compliant. It works fine on all my / client Lenovo machines with Intel networking.

I agree and will keep this in mind for future reference as I suspected as much. However, for the time being I am able to work efficiently and that is my first priority.

Thanks again for your help.
