Reading .eml files in Win7

I use webmail (Google) however some of my colleagues insist on using MS Outlook.

 Often when I get an email from them that contains another email that they forwarded the additional message arrives in an attachment called noname.eml

 This freaks me out ... and I have spent much time looking for an app that will read these files (there are some available but I can't really recommend any that stand out as being an elegant solution for me).

I stumbled onto a very simple solution today.

1. Simply download the file (noname.eml) from your original email
2. Rename it to noname.mht 
3. Open it with Internet Explorer 

 No need for any additional software .... which suits me.
