Troubleshooting Safe Exam Browser: resetting Safe Exam Browser after a crash


In some cases, you may not be able to shut down or restart your PC after using Safe Exam Browser (SEB), and Ctrl-Alt-Del does not show the Task Manager either.


While running, SEB changes Windows Registry settings for the options in the Windows Security Screen invoked by Ctrl-Alt-Del. These Registry settings are nor properly reset to the original values in case

  • your PC would be force reset while SEB is running,  or
  • SEB has crashed.  


Run the following tool in your Program Files directory: SafeExamBrowser\SebWindowsServiceWCF\SebRegistryResetter.exe

This will result in the Registry settings being properly reset, and you will be able to shut down or restart your PC again.
