Eazel

Eazel was a Windows compression program. It advertised support for its own format, with the extension ".eaz", which it heavily implied to be proprietary; however, this is actually just ZIP, or, at any rate, a variant thereof which seems to be functionally indistinguishable when reading. At some point before version 3.01 (date unknown), "EAZ" was dropped, and the program itself seems to have become a frontend for 7-Zip (more likely is that this occurred upon the introduction of versions 2.0 or 3.0, in 2010-2011 or 2012, respectively; however, no working copies of these seems to be available online); Eazel itself entirely stopped being updated in 2014.

Eazel is capable of producing and opening self-extracting archives.
