and are the same thing, at least according to the questions.

Shouldn't these two be merged (if possible) / made synonyms?

  • The older version uses the mswmm file extension while the other uses the wlmp file extension. They are not compatible with each other.

I just want to note that the two are not really the same thing.

The Windows Live label was introduced at some point and the Windows Movie Maker got a drastic overhaul, losing features and compatibility in the process. From Wikipedia:

Windows Live

A new version of the software, renamed Windows Live Movie Maker 2009, was released as a beta on September 17, 2008, and officially released as a standalone product through Windows Live Essentials suite on August 19, 2009. This was effectively completely new software as it could not read projects created by earlier versions and did not support custom XML transitions written for the previous versions. In addition, a great many features were removed.

    Here's the thing. WLMM is different from pre-WLMM WMM, but recently WLMM was renamed back to WMM, so post-WLMM WMM is still called WMM but different from pre-WLMM WMM. And you get a cookie if you manage to read that without getting a headache.

  • Sorry, I never knew that they were actually different. I always thought the 2 were part of the Windows Live 'suite' and over the years it had shortened to WMM. Sorry for the waste of time, should I delete this 'question'? Commented Jul 7, 2014 at 19:36
  • Should I remove the 'tag-synonym-request' tag? But keep the question in case future users think this is the same thing, like I did. Commented Jul 8, 2014 at 18:18

  • Should I add the 'rejected' tag as well? Commented Jul 8, 2014 at 18:22
  • @shub Only moderators can add that tag Commented Jul 8, 2014 at 18:22

An interesting thing is, the older versions of WMM are actually not WLMM, which was new and introduced with 7 (and breaks backwards compatibility with the old project files). IIRC, WLMM also has less functionality than WMM. So, they're not really the same thing.

On the other hand, with the release of 8, WLMM was renamed back to WMM - and this new WMM is different from the old XP/Vista-era one. If there's a merge/synonym at all, WLMM should go be merged into WMM, the more general and current name.

  • I never knew that. If they're not the same, we shouldn't do anything to the tags then I think Commented Jul 7, 2014 at 19:33

It should just be called movie-maker.

    No, it shouldn't because the two are not the same (as the other 2 answers say). Commented Jul 19, 2014 at 11:28
  • ^Not only that, but having just [movie-maker] makes it a very generic tag that is open to misuse on questions unrelated to the Windows Movie Maker (either version)
