This morning (08/22/2014), as I switched to Windows Live Mail, I noted that my Log-In ID for Windows 7 was captured and printed in the Live Mail search window!  Am fairly certain this is not supposed to happen, and I do not recall it ever happening before; but I might not have noticed it earlier.

I run Windows 7 Home Premium 64-bit with SrvcPk1 on a Gateway DX 4350, AMD Phenom II X6 1055T Processor with 8GB Ram.

Had just logged out, logged back in after boot-up (apps seems to run faster this way), and logged in to Windows Live Mail, though Windows Live was already up in background.

At the top above the email pane, my Log-In ID was already captured and printed in the "search for a message" input window.  Another security breach?  Thanks for your support.
