  1. Good information, as always, and a nice tip.

    I would caution anyone to always create a backup prior to any registry edits — even an addition such as this.

    Keep up the great work, Abhishek

      Yes, I agree, I missed a big point which your experienced eye caught: Take a backup before hand.
