Windows Live Mail – latest version?

I am currently running Window Live Mail (WLM) 2011 under Win-Vista.  In anticipation of "upgrading" to Windows 10 soon, I would like at the same time to install the latest version of Windows Live Mail.  As far as I can determine, that would be WLM 2012, support for which ends later this year.  Nevertheless, I have auditioned the email client in Windows 10 and find it seriously deficient when compared to WLM.  What I would like to do is to download WLM 2012 for use under Windows 10, once I migrate to that OS.  But this may be after support for WLM ends.  Can I download now under Win-Vista, save the file, and simply run the installer later-on, once I have Windows 10 up and running?  Or will the installer 'phone home' for files that will have been taken down by that time?  Thanks!
