k then in that case Windows 2000 and below would be abandonware
Nope. None of the Microsoft operating systems are abandoned when it comes to copyright protection. They are no longer supported, but as far as copyright:
"As a general rule, for works created after January 1, 1978, copyright protection lasts for the life of the author plus an additional 70 years. For an anonymous work, a pseudonymous work, or a work made for hire, the copyright endures for a term of 95 years from the year of its first publication or a term of 120 years from the year of its creation, whichever expires first."
I tried looking for a place to buy a digital version of Windows 95 online, but I can't find anything. I'm not sure what stores would even sell it anymore.
