Internet Explorer 11 extreme slow

I have a very annoying issue with a pc in the production area.
During the last 2 month the IE 11 browser has become extremely slow.
It seems to be a general problem.
I have tried to do a default reset + a system restore but the problem persists.

I have several applications installed which I can not reinstall if I the PC must be reinstalled.

The PC is a Dell Optiplex 3010 with Windows 10 and 8 GB ram.

Have you tired to uninstall antivirus / Internet security software, restart computer and do a test?

Build no of Win 10?

Brand and version no of antivirus / Internet security software?

Also, try to download and install Autoruns by Microsoft to troubleshoot auto start software or service.

What about other browsers on that machine? make sure you cleared out all the temporary internet files, clear %temp% etc. Also, remove the unwanted plugins/add-ons (IE>>Tools>>Internet options>>Program>>Manage add-ons)

If other browsers also experience slowness, you need to do a TCP/IP reset and DNS cache reset in elevated command prompt.

By default, "Edge" is Windows 10 default browser,   Have you tried Edge browser with the same experince ?

You need to uninstall, disable has no effect.

What is the version of Trend Micro Worry free?

Also, you can start the computer in safe mode first to do a test.

If safe mode works, the problem is caused by malfunctioned antivirus software and you need to uninstall it. Read the article below on how to go to Safe Mode in Windows 10.

If you have installed  "Trusteer Rapport" software (recommended by many banks for online banking security) uninstall it and verify the status.

1. Is it possible to downgrade IE to the last working configuration and test it?

2. What about other browsers and other applications? Are they extremely slow too?

3. Have you tried it with another profile?

4. Go to C:\Program Files\......iexplore.exe and run it directly from here, not via shortcut. Results?

The first help for slow computers (not in this order):
Run Disk Cleanup
Check out Startup items (Task Manager)
Check AV activity
Check RAM and CPU
Run deep virus scan

You might also try this:
Perform clean boot without any services and startup items. Results?
Get into Safe Mode and run what you need. Results?

Try running a Windows 10 Repair Install and Keep Everything.

Go to the Media Creation Link

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