Last week the first major update to Windows 10 rolled out to the public, which introduced a range of changes that had been tested by Windows Insiders in the previous months. The next large-scale update, code named 'Redstone’, is scheduled to arrive next year and development of this release is already underway.

Last week members of the Windows Insider program began to see small hints of the Redstone update within the Windows 10 settings menu. After the RTM version of the 'November Update' was distributed among testers, a 'rs1_release’ branch appeared to many, which hinted the preview may be closer than initially thought.

Earlier today a cumulative update (KB3118754) was released for Windows 10, implementing small tweaks to improve upon last week's changes. With this update, it now appears that Windows Insiders are now being enrolled to the 'rs1_release' within their registries.

This change can be seen if enlisted into the Windows Insider program, under the following path:

Redstone is scheduled to release in two waves over the next year, with the first wave rumored to arrive next summer.
