Now let's see if we can sort the Windows Security Center issue. We ran Dial-A-Fix, so let's see it the the registry will merge the key.
Do you still have the LEGACY_WSCSVC.reg file on the desktop? If you don't, go back to post #35 and download it to the desktop again.
Close all open browsers ans windows and right click on the LEGACY_WSCSVC.reg file and click Merge.
OK any prompts you might get.
If you get a message saying the file merged successfully, reboot the computer to make the changes effective.
Let me know what happened.
