QuestionWhat about Windows 8? How does one get rid of Java update notifications for this version?Community AnswerFollow the same steps, but instead of the suggested Step 1, go into the main menu with the tiles of W8, and type in 'msconfig' there. The App-search should give you an option to get to the msconfig.

QuestionDo the steps above apply to the Supremo download as well?Community AnswerThe steps suggested should work for every version. The name of the program (Steps 3 to 5) might be a bit different. Look for any name including "Java" and "auto update."
