Update: Microsoft has pushed out another update for Windows 10 Insider Preview Build 18356.16 in the Slow Ring.
The build includes KB4496796 and takes the OS to Build 18356.21 and brings those on Build 18356.21 who were having difficulties updating to a new build to a good state so they can update to Build 18362.
Once KB4496796 has had enough time to roll out Microsoft will offer Build 18362 to those users.
19/3/2019: After many months of basically ignoring the Slow Ring, these last few weeks Microsoft has been flooding that channel with new builds. Today (19/3/2019) Microsoft has updated Windows 10 Insider Preview Build 18356 to 18356.16 in the Slow ring.
This Cumulative Update is designed to help Microsoft test their servicing pipeline with larger updates and actually contains nothing new. Microsoft simply updated the version numbers of several components in the OS.
The build has previously been mildly updated to 18356.1 on the 15/3/2019, but the changelog remained the same, including new support for Android screen mirroring via the Your Phone app.
Insiders can now mirror their Android phone’s screen directly on your PC without having to dig for your phone.
The new phone screen feature gives you easy access to your phone apps on your PC. The feature will gradually roll out to Insiders on 19H1 builds. It may take a few days for this feature to show up inside the Your Phone app (version 1.0.20701.0 and above).
You can use the Your Phone app on any Windows 10 PC running Windows builds 1803 (RS4) or newer and any Android phone running Android version 7.0 or newer. The new phone screen feature is initially only compatible with a limited set of devices. Surface Go will be the first device in the Surface lineup to preview this feature. Microsoft will continue to expand the list of devices over time for both the PC and phone.
Phone screen requirements:
- Select Android phones* running Android 7.0 or greater (*Samsung Galaxy S8/S8+/S9/S9+).
- Windows 10 PC with a Bluetooth radio that supports low energy peripheral role. How to check if your PC supports this.
- Latest 19H1 preview build (18335+ recommended).
- Android phone must be on, within Bluetooth range of the PC, and connected to the same network as the PC.
- Touch input doesn’t work yet
- Always on display will not be shown on the phone screen displayed on the PC
- Blue light preferences will not be applied on the phone screen displayed on the PC
- Audio will play out of the phone speakers, not the PC
- Double clicking may bring down notification center
- Some games and apps do not support mouse interactions (e.g. Pokémon Go, Merge Dragons, Feedly)
- If you turn on the setting to hide soft keyboard when a physical keyboard is present your soft keyboard will disappear whenever you’re within Bluetooth range of your PC regardless of the state of the Your Phone app or phone screen session
For everyone else, the update brings the following general changes, improvements, and fixes for PC

Known issues for Developers
- If you install any of the recent builds from the Fast ring and switch to the Slow ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
Windows 10 Insiders in the Slow Ring can download the update by Checking for Updates in Settings.
