  1. The Dump file: section of the Startup and Recovery window allows you to set the location where new memory dump files are saved. The %SystemRoot% string is a Microsoft Windows variable that stands for the root directory of your Microsoft Windows installation (typically the default value is C:\Windows).

    In the Write debugging information section, you can select the type of memory dump (we recommend that you use the Complete setting, see Figure 1-4).

  1. Close Registry Editor and restart your computer.
     
  2. Once your computer has started, press and hold the right CTRL key on your keyboard (you must use the right and not the left) and then press the Scroll Lock key (located in the upper right on most keyboards) twice. The Windows forced crash dialog will run and a memory dump will be generated. Your computer may restart as a result.
     
  3. Once your computer has started, navigate to your system's root directory (C:\Windows by default) and locate the file named MEMORY.DMP. Respond to the last email from your case with ESET Customer Care and notify them that you are ready to submit your memory dump file. An ESET Customer Care agent will contact you with instructions to submit the file for analysis.
