OK to update the Junk Email Filter?

I have Vista Home Premium. Thanks for the blanket OK to install updates for Windows Defender and the Malicious Software Removal Tool, but what about Windows Mail Junk Email Filter?

I never used Outlook or Outlook Express or anything MS email related. Should I update these?

If you don’t use Windows Mail, Windows Live Mail, Outlook or Outlook Express, you don’t need to update the junk email filter. But I wouldn’t lose any sleep over it. The updates are generally innocuous.
