Once there was a time were applications weren't forced to go online, because not everyone was able to be online. You needed registration keys for most of the software and at this point the demo scene came in.

I really like those key gens (key generators) with a small 2D or even 3D animation, midi sound and the actual key generation.

But like 10 years ago, Windows (or was it an antivir app?) started to delete those without asking me, because it recognized it as malware (yeah, sure...)

I once collected them, because for me they were some kind of cool collectible art (not like this NTFs bullshit). But I lost all of them at once.

Is there someone who collects them or is there even a publicly accessible place to watch them?

btw. stuff like this was one of the reasons to never use Windows again.
