It should be no problem for anyone running old/legacy software on their current OS, as long as they don't open up vulnerabilities or whatever. Most times, the older stuff is better (and easier) than the newer stuff. I use a few myself as by this short list below: Microsoft FrontPage 2003 - I've always been a user of this program ever since I had my first computer, with the 2000 edition. Always liked to save my documents for web viewing. Paint XP and Windows Movie Maker - When I first had this current system, I hated 7's own Paint and Live Movie Maker from the start and just by chance there's XP-styled versions for the OS. Virtual PC 2007 - I simply find this easier than VirtualBox, although when I first installed it the OS complained that it may be incompatible. Turned out it actually was. Inkscape 0.48 - Slightly more recent even though this was from 2013. I did update it to a later version but thankfully it didn't overwrite the older one, because I found the newer version rather fiddly and not quite the same. To be honest, I don't use it all that often. Only if I'm in the correct mood for design work. I did have a WinRAR version from 2011 (can't remember the version number) but it had to be upgaded to v5.70 when I found out there was a vulnerability connected to it. So, how about you?
