but there is probably many original install CD's available for Win 95. You could try eBay, or perhaps your friends or relatives may have the original disks lying around somewhere.
But if you mean "copy" of Win 95 CD's, then I doubt Microsoft would be very happy about pirating issues, even with such an old OS.
I wonder if it is likely to get a free copy of Windows 95 or earlier. I am just inquiring here. I used them in the past and feel like experience them for a second time.
