With only a couple of weeks before the official release of Windows 10, Microsoft has announced that builds of the operating system used in the Insider Program will no longer be available for download, beginning tomorrow, July 14th. This means that builds 10162 and 10166 will no longer be offered over Windows Update, the 10162 ISO file will not be on the Insider site, and pre-release keys will no longer activate builds.
This suspension of downloads is only temporary, and new builds are going to be available through the "production" channels that will be used in the main rollout of the operating system. The reason for this move is because Microsoft needs their Insider volunteers "to be using, stressing, and validating our distribution and upgrade processes."
New ISO files will also be made available in the future.
Obviously, Microsoft is very close to a public release of the operating system. If you haven't got one of the builds used in the Insider Program and wish to participate, you'd best download one quickly, as they will be gone within the next day.
You can read the announcement at the Windows Blog.
