my windows security center will not work properly.then i followed the following steps. when i am open the service.msc then it shows your current security systems prohibit running active x control in this page or you have blocked a publisher of one of the controls. it causes my windows gadjet does not work properly and i can't restore my system to an earlier point.
Click Start, write "services.msc", right-click and "Run as administrator", search for "Security Center" and double-click it and on "Startup type" select "Automatic (delayed)". Enjoy!
