SOLVED: Internet Explorer 11 Stops Working Because of iertutil.dll

Quite a few Windows 10 users have reported a problem where Internet Explorer 11 crashes on them whenever they have more than one tab open and either switch from one tab to another or close any one tab. The error message users affected by this issue receive states that “Internet Explorer has stopped working”, followed by something about collecting information. One of the best features of the Windows Operating System is that users can find out the cause behind any of their applications crashing by simply going into Reliability History and taking a look at the event log for the program in question.

When an affected user goes into Reliability History (by opening the Start Menu, searching for “reliability history” and clicking on the search result named View reliability history) and looks at the incident report for the Internet Explorer crash, they see that the faulting module is iertutil.dll. The iertutil.dll module is the Internet Explorer Run Time Utility library and is essential for the appropriate functioning of Internet Explorer 11. This issue is most commonly caused by a corruption that affects the iertutil.dll module. Thankfully, though, this problem is entirely fixable, and here’s what you need to do in order to fix it:

Phase 1: Fixing any and all corruptions affecting the iertutil.dll module

Wait for the command to be fully executed, and once it has, it will reveal whether or not it found any issues and whether or not found issues were fixed.


Restart your computer.

Pro Tip: If, after running the command described above, it is revealed that one or more found problems were not or could not be fixed, simply repeat all of the steps listed and described above after restarting your computer.
