A family of Microsoft word processing software products for creating web, email, and print documents.
The current version, regardless of name, will view documents created in any version of Word, provided you also install the Compatibility Pack. It is not specifically a Word 2007 or 2010 viewer because it does require the addition of the Compatibility Pack to work.
If by "end of life" you mean that no further updates will be issued for it, then possibly that is the case, but since this "latest version" was released in 2012, it should be pretty up-to-date.
