When I turned on my WinXP tonight I noticed that the MSE icon at bottom of screen was now "YELLOW" instead of the usual "GREEN." When I opened the MSE, it too had "YELLOW" border and 'warning' about MSE being discontinue for WinXP.

#1- Is my MSE still protecting my WinXP System, even though it is now colored "YELLOW?"

#2- How will I know when it is NOT protecting my WinXP System?
