A new build of Windows 10 has leaked online, directly from Microsoft's update servers. Unfortunately, the image is encrypted with a new key making it virtually useless for now.



From Neowin:

Build 10061 can be downloaded through a Windows Update link, but can’t be installed. Though the image is official and untampered with, it can’t be installed because of the encryption. Previous leaked builds were usually decrypted with same RSA key, but it looks like Microsoft has made some changes and that no longer works.

Interestingly enough this build is the same one that showed up a week ago, directly in Windows Update for some users, though it didn't install then either.
