Microsoft can't handle its own Word documents.  On top of that, it provides totally wrong advice.

I just bought a new computer and found out that the default settings for email attachments in Windows Live Mail are set to block all Word documents.  Wow!  Microsoft doesn't trust its own documents!

Then I clicked on "Help" (within the email with the blocked Word document), and this led me to this page: http://windows.microsoft.com/en-us/windows-live/mail-email-download-attachments-troubleshoot-ui

The advice there is to ask the sender to ZIP the Word dovcument and sent it as a ZIP file.   Wow!  Double WOW!  If any email attachment should be suspicious, it should be a ZIP file, because it's ard to tell what might be hidden within the ZIP file.  The ZIP file could easily hide a malicious executable file.  I tell all my friends to never click on ZIP file unless they are absolutely sure it comes from a trusty source.  And even thn, is that really an email from your trusty source, or is someone just hijacking their email address?

I can't believe that Microsoft recommends ZIP files over DOC files.

Microsoft seems to be going down the hill fast.
