We previously published a series of methods for preventing and eliminating Internet Explorer crashes. These include disabling add-ons and resetting the browser. We’ve now identified two additional procedures that can, in many cases, prevent crashes from reoccurring.
Kill IEUSER.EXE task Launch the task manager by pressing control-alt-delete, then launch Internet Explorer. Immediately after the browser launches, end the process “IEUSER.EXE” in Task Manager.
Turn off protected mode While this shouldn’t be your first course of action, as it could create serious vulnerabilties and open your system up to attack, several users have reported that turning off Internet Explorer’s protect mode resolves persistent crashes. To do so, click the Security tab, select a Web content zone, and then change the “Enable Protected Mode” check box to disabled for the desired items.
