Shouldn't be soo quick to jump at the first link that says it's a leak of Windows 9. The first one never is. Where do you see that it came from WinFuture? Anything can be added to the name of an ISO. You need to get that in your head. Take a Window 7/8/8.1 ISO and rename it using parts of a legit Windows 9 build number. Throw the link out there and watch how fast it gets ate up by people with zero patience
Anyone have any guesses about when the invites for the press event? As I mentioned earlier, based on the two week prior notice for Surface events, I'm betting we'll hear something from Microsoft on 9/16. Furthermore, I have a feeling whenever screenshots are released of a Windows build, the entire build tends leaks a couple days later. (Does it?) So perhaps it will leak the same day the press events come out? Yeah. I have looked up things before on torrents and there's always fake torrents. I'm sure there were fake torrents before the screenshots, but once the screenshots came out people tend to believe the fake torrents are actually legitimate. Looks like we're on the same boat now aren't we?
I contacted my friend on phone and he told me he had a modded Windows 8.1 as Windows 9 with build 9788 iso.
