No its not a free trial, it is the proper product, it's just the 2006 version

To get it you have to sign up (and if you wish) download the trial version of the current one. I skipped that step though. I've been using it for maybe 4 years on Win7, 8 and now 10 and nothing expired on me I also took the Mac version although that was even older. Still works fine for editing though.
