Help, This day I want to update Windows by enabling the "Automatic Update Service" through services.msc. I realize, this service is missing. Those registry may be deleted by virus etc. I still found wuauserv.dll in C:\WINDOWS\system32 I start googling, hope that i can find some registry to restore this "Automatic Update Service" but still no luck. How about merge a wuauserv.reg from the healthy OS? Can u tell me how to fix this? Im XP SP2.
