[SOLVED] Curious on if I need to worry about this

I just scanned my pc with MBSA 2.2 x64 on Windows 7 Professional SP1 x64 and am wondering if Ishould worry about it. MBSA 2.2 x64 is showing HomeGroup and my Xbox 360 extender as not having any expiration dates for there passwords. I only use one pc, so should I worry about this ? Secunia PSI says everything is patched,

Not really a big deal.

That's what I was thinking. Just wanted to double-check to be positive.
