Hello Khalid,

Error message when you try to start Windows Defender on a computer that you
recently upgraded to Windows Vista: "Application failed to initialize"

Is there any better solution? Re-installing Vista doesn't sound too
thrilling, and I'm afraid that if I do a system restore that far back (I
don't know exactly when this issue started, but I am guessing as far back as
when I upgraded to Vista in May), I could be losing important files...no?

Just an inquiry you upgraded from what Windows Version to Vista? Is there by
any chance on such upgrade there was an installed Windows Defender?
