What's the earliest people have tried? I've had a go of one of the 6.1.69xx series a long time ago, but were the earlier ones leaked at all?

have no idea

i didnt wanted to give any chance to the Seven coz was having troubles for ages with microshit corp great products like winslows and winshit till oneday somehow i downloaded and installed 7057 as prior os lol

i guess there no any reasons with trying earlier builds anyway , they r much raw

The earliest leaked build was 6519.

Was that much different from the Windows 7 we know and love today? From what I can tell from that list, it looks like some of the pre-milestone 1 builds were from 2005!

6519 looked and functioned almost exactly like Vista. There were minor differences, but nothing that made you think "this is more than a service pack."

Obviously Windows 7 has come a long way.
