In October 2018 Windows Update servers will begin delivering Windows 10 version 1809 to current installations of Windows 10 that have been running for at least 30 days. Each time there is a feature update, Microsoft adds and/or removes other features.
As of this writing, here are some of the removals slated for 1809:
1. Disk Cleanup Tool
The Storage Sense feature that came with the recent Windows 10 v. 1803 works almost the same as the familiar Disk Cleanup Tool. However, the feature is currently turned off by default. To enable and configure Storage Sense from Settings options:
Click Settings > System > “Change how we free up space automatically”. This will open the Storage Sense settings on your PC. Simply turn it on so that it will be ready to use.
2. Snipping Tool
The Snipping Tool, a favorite of many, has been replaced by the Screen Sketch Tool which includes support for freehand screenshots as well. There will be a shortcut in the action center for this.
3. Business Scanning or Distributed Scan Management (DSM)
There are no devices which now support this technology. This was a function of Windows Server 2008 R2 were devices which could scan, where integrated into the document workflow of an organization.
4. Font Smoothing setting in unattend.xml
The mention of FontSmoothing in the unattend.xml file will be ignored. It is not necessary because Windows 10 now uses ClearType. Previously, this was used to specify whether font smoothing is enabled, and which type.
5. Hologram app
The Hologram app is used to view the 3D paintings created using Paint3D. Windows 10 uses the Mixed Reality Viewer instead.
6. Trusted Platform Module (TPM) management console
Microsoft has moved their Device and Security to Windows Defender. The information which was previously available through TPM console, can now be seen in the Device security page in the Windows Defender Security Center.
7. limpet.exe
This tool was used to access TPM for Azure connectivity. It will be open source now so that other developers can meet the needs of users who may want it.
8. Phone Companion
All the features that were available with the Phone Companion App will be available in a new Phone Page App.
9. Future updates for Windows Embedded Standard 8 and Windows Embedded 8 Standard
The WEDU update server will stop pushing new updates. Therefore, updates for Windows 8 Embedded version, will need to be manually downloaded from the Microsoft Update Catalog.
Microsoft has also stopped developing Companion device dynamic lock APIS and OneSync service because their functionality is now available in other Windows 10 components.
If you have feedback about the proposed changes, you can use the Windows 10 Feedback Hub.
