In case the Chrome icon is on the Taskbar of your computer, right-click on Chrome icon, right-click on Google Chrome and then click on Properties.
   
2. On the Chrome Properties screen, click on the Target text box and scroll to the end of the line. Insert the phrase –process-per-site after the end of the text which is currently in the Target box.
   

   Note:

   • There must be a single space before –process-per-site
