Will it ever be OK to copy Windows 95/98 or will Microsoft own the rights all the time?
I just woundering if I could download it, or if I need to buy it from ebay or simillar?

It is legal to make an archive copy of any version of Windows. It isn't legal to install more than one instance at a time using the same license (key). As a practicality When 95/98 were released there was no real way to prevent multiple installs using the same key.
Technically, there is no statute of limitations on software. Unless M$ officially releases it for free, the EULA is still binding. That being said, why would you even consider paying for Win95/98 in 2013? Just download it from the torrents & don't worry about it.
I edited my response above. The source should be the EULA. Try reading it for Win98SE:
If you can find one cheap enough on eBay then it would be safer than torrents and it might even be legal. You need one with a product key to save you searching for one. You can definitely find free downloads out there (even without using torrents). You need to try harder with Google. You would then need a product key.
Always pop back and let us know the outcome - thanks
