This is of course Software Piracy . The developer of the app has no rights to distribute Windows 95, and I'm a little surprised that the app has not been removed from GitHub yet. And now the app is just a toy; There is no real reason to use Windows 95 like this, except for the novelty factor that actually works.
But Windows 95 (and software running or requiring Windows 95) was an important part of computer history. I think it could be made the case that it is Microsoft's most important Windows version of all time, and its influence is still felt today. Not only was it technically an important step out of the world of 1
Systems like these are important to get these important parts of computational history. And yet there is no effective way to develop and disseminate it without violating copyright law. This, of course, is the same problem in the console emulation world, but with even greater historical impact: games are important cultural artifacts, but authentic access to Windows 95, Office 95, Netscape 3 (and the web content of that era), and so on more importantly, because of the greater influence that these things ultimately had.
The software industry has at best shown indifference to preserve and protect this legacy, and hostility in the case of ROM games. As silly as the Windows 95 emulator is – it's basically put together for fun – it serves a purpose that's becoming increasingly important. Rightholders and legislators should work to ensure that such work is at least legally or better actively supported by the industry itself. If they do not do it? Our recent history will be lost and inaccessible to the detriment of all of us.
