Thanks for pointing that out! Fixed
That's a darn shame... oh well, I never was too big a fan of Avast myself to be honest. I still run an older version of MSE along with the last major version of Malwarebytes for XP/Vista, both of which still receive definition updates which is what really matters (Avast will still receive definition updates on XP/Vista too )
Anyway, aside from Avast/AVG, I have found a couple of pieces of software that no longer support Windows Vista:
1. OBS Studio, a popular livestreaming software, no longer supports Windows Vista after 21.0.1 (released Jan. 2018), so this version has been added to the list:
2. Dolphin, a popular GameCube/Wii Console emulator, hasn't officially supported Windows Vista for quite some time. Despite this, the latest "Stable" release (5.0) along with new "Development" releases continued to work on Windows Vista until a certain point at which I cannot exactly pinpoint, since there are so many versions that have been released since the last time I tested Vista compatibility. For this reason, I have simply listed the last "Stable" version to work with Vista for now:
Also, I have added a couple of new pieces of software that continue to support Vista to the "Video & Photo Editing Software" section (thanks to @i430VX for showing me these):
