I am running Windows 7 Professional on an HP Elite 8000, Intel Core II Duo quad, 12 gig DDR3, 6 terabytes of HD storage. At least once a week I will get a flag on my task bar from the Action Center telling me to reset my update preferences. When I open the Center, it shows Windows update in the manual mode. I reset preferences and the flag goes away. The next day or next week, I get a flag and the same message. What is changing my Windoews Update Preferences?
