Supersite for Windows posted What we know about Windows 10 Service Release 1 (SR1)
A quote from the article:
When our own Rod Trent returned from attending the Windows Insider and Windows 10 launch events in New York City last week he shared some insight he gained during the various conversations he participated in.What we know about Windows 10 Service Release 1 (SR1) @ WinSupersite
One of the big pieces of info was the reminder that Windows 10, the release everyone is receiving after 29/7, is the beginnings of this new OS. Windows as a Service (WaaS) is a term that has been used to describe this process of keeping the OS up to date and continually improving it.
It was also reiterated that Windows Insiders are a big element of this WaaS process and will be testing updates before they head out to the general population. Just yesterday the ability to opt into receiving Insider builds is once again live and the next build should arrive soon for testing.
