Windows 7: Security Center Fail, Error code: 0x80070424

01 May 2013   #1

Windows 7 Ultimate 64-bit
Security Center Fail, Error code: 0x80070424

Hello! I was checking my Laptop's health this month and I was so surprised to see the Window's defender is not started. I clicked the "Start Now" button but a window says: "Windows Defender cannot be started". I checked the firewall. The Private and Public network firewall is off. I turned them on. I opened the windows defender again and clicked the "start now" button. A window appeared. Now it says: "The specific Service does not exist as an installed service. (Error Code: 0x80070424). I also tried using the "Windows Update". It's almost several months since I last got an update. And as far as I know, I set the option to "Notify me when new updates are available". I opened control center and windows update. But the windows update panel says: "Always install updates to enhance your computer's security and performance". I clicked the "Check For Updates" button. But another window says: "Windows update cannot currently check for updates, because service is not running. You may need to restart your computer." I checked the services. The Security Center has been started. But "Windows Defender" & "Windows Update" was not on the list! I scanned for malicious programs with my own Antivirus. I found some threats. But definitely that's a low threat and it wouldn't make changes on my system (because I always check each file before opening). Please help!
