Microsoft also announced a new ring for Windows Insiders (for both PC and Mobile).
It is called the Release Preview Ring.
This ring is for those who want to keep getting updates on the 10586 build (Windows 10), just like the last couple of builds (10586.71 and 10586.104).
Microsoft will soon push out its first Redstone Windows 10 build. Actually they already pushed out the first one for PCs last week (Build 14257).
Redstone, is the codename given for the next major update for Windows 10, and it is scheduled to be offcially available later this year.
It will come with a whole new set of features (including extensions for the Edge browser and more).
Microsoft has already begun testing these new features, so if you want to get early access to the "Redstone" builds, you will have to be on the Fast Ring. Be careful though, because while you wioll get early access to new features, it will be plagued with bugs, lots of bugs as well.
If you want to remain on the current Windows 10 OS Builds, then the Release Preview Ring is the one you should be on.
Slow Ring is also available for those who want the bugs ironed out first before downloading any builds.
So here is a summary of the 3 Rings...
The 3 Windows Insider rings are:
- Fast – Best for Insiders who enjoy being the first to get access to builds and feature updates, with some risk to their devices in order to identify issues, and provide suggestions and ideas to make Windows software and devices great.
- Slow – Best for Insiders who enjoy getting early access to builds and feature updates, with less risk to their devices, and still want to provide feedback to make Windows software and devices great.
- Release Preview – Best for Insiders who enjoy getting early access to updates for the Current Branch, Microsoft applications, and drivers, with minimal risk to their devices, and still want to provide feedback to make Windows devices great.
