Microsoft released Windows 10 build 10586.122 for PC a day before when they announced the same build for Windows 10 Mobile also. But this build is only for Insiders who has enrolled to Slow Ring and Release Preview Ring. Many of the users who are on Fast Ring will not be able to see this until you do a some configuration. You can read the complete changelog here.
The current build release 10586.122 is limited for those who has enrolled for the Slow Ring and Release Rings of the Insider program as Fast Ring is limited to newer devices only which are Lumia 550, 950, 950 XL and the Redstone releases devices, which are same.
How to Update:
This update will be a bit tricky. Here is how you can update,
- If you are on the Insiders Fast Ring but not on Restone you will need to switch configuration rings to Insiders Slow or Release Preview to get build 10586.122.
- If you are on the Insiders Fast Ring but not using a Lumia 550, Lumia 950 or Lumia 950 XL you will need to switch rings to Slow or Release to get build 10586.122.
- If you are on Redstone release (Fast Ring) you will need to roll back the OS and then enroll again using insiders app in Slow or Release rings.
