Windows 10, version 1809 Features removed or planned for replacement

Here is a Blog from Microsoft about changes to Windows 10 1809.

Features we removed in this release

We’re removing the following features and functionalities from the
installed product image in Windows 10, version 1809. Applications or
code that depend on these features won’t function in this release unless
you use an alternate method.

Feature Instead you can use…
Business Scanning, also called Distributed Scan Management (DSM) We’re removing this secure scanning and scanner management capability – there are no devices that support this feature.
FontSmoothing setting in unattend.xml The FontSmoothing setting let you specify the font antialiasing
strategy to use across the system. We’ve changed Windows 10 to use ClearType
by default, so we’re removing this setting as it is no longer
necessary. If you include this setting in the unattend.xml file, it’ll
be ignored.
Hologram app We’ve replaced the Hologram app with the Mixed Reality Viewer.
If you would like to create 3D word art, you can still do that in Paint
3D and view your art in VR or Hololens with the Mixed Reality Viewer.
limpet.exe We’re releasing the limpet.exe tool, used to access TPM for Azure connectivity, as open source.
Phone Companion When you update to Windows 10, version 1809, the Phone Companion app will be removed from your PC. Use the Phone page in the Settings app to sync your mobile phone with your PC. It includes all the Phone Companion features.
Future updates through Windows Embedded Developer Update for Windows Embedded Standard 8 and Windows Embedded 8 Standard We’re no longer publishing new updates to the WEDU server. Instead, you may secure any new updates from the Microsoft Update Catalog.

Features we’re no longer developing

We’re no longer actively developing these features and may remove
them from a future update. Some features have been replaced with other
features or functionality, while others are now available from different
sources.

If you have feedback about the proposed replacement of any of these features, you can use the Feedback Hub app.

Feature Instead you can use…
Companion device dynamic lock APIS The companion device framework (CDF) APIs enable wearables and other
devices to unlock a PC. In Windows 10, version 1709, we introduced Dynamic Lock,
including an inbox method using Bluetooth to detect whether a user is
present and lock or unlock the PC. Because of this, and because third
party partners didn’t adopt the CDF method, we’re no longer developing
CDF Dynamic Lock APIs.
OneSync service The OneSync service synchronizes data for the Mail, Calendar, and
People apps. We’ve added a sync engine to the Outlook app that provides
the same synchronization.
Snipping Tool The Snipping Tool is an application included in Windows 10 that is
used to capture screenshots, either the full screen or a smaller, custom
“snip” of the screen. In Windows 10, version 1809, we’re introducing a new universal app, Snip & Sketch,
that provides the same screen snipping abilities, as well as additional
features. You can launch Snip & Sketch directly and start a snip
from there, or just press WIN + Shift + S. Snip & Sketch can also be
launched from the “Screen snip” button in the Action Center. We’re no
longer developing the Snipping Tool as a separate app but are instead
consolidating its functionality into Snip & Sketch.
