IE Per-User Initialization Utility has stopped working after IE11 installed

Hello Filbert,

Thank you for posting your query on Microsoft Community. We are glad to assist you.

I am sorry to hear that the problem occurred after updating to internet explorer 11.

I would appreciate, if you can provide us the following information to help us understand the issue better?

1. Are you able to access the websites using IE 11?
2. Which security software is installed on the computer?
3. Do you get this error message on startup? If yes, is it after booting to the desktop?

I understand the inconvenience that you have to go through due to this issue, however, let’s try to put the system in clean boot to check if you receive the error message. 

Perform Clean Boot.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.

Note: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting

I would also like you to provide us with the Event Viewer logs which will help to understand the issue better.

Hope the information helps. Let us know if you need further assistance with Windows issues. We will be happy to help.

Thank you
