| Wi-Fi WEP and TKIP | Since the 1903 release, a warning message has appeared when connecting to Wi-Fi networks secured with WEP or TKIP (which are not as secure as those using WPA2 or WPA3). In a future release, any connection to a Wi-Fi network using these old ciphers will be disallowed. Wi-Fi routers should be updated to use AES ciphers, available with WPA2 or WPA3. | 1903 |
| Windows To Go | Windows To Go is no longer being developed. <br><br>The feature does not support feature updates and therefore does not enable you to stay current. It also requires a specific type of USB that is no longer supported by many OEMs.| 1903 |
| Print 3D app | Going forward, 3D Builder is the recommended 3D printing app. To 3D print objects on new Windows devices, customers must first install 3D Builder from the Store.| 1903 |
|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](https://docs.microsoft.com/windows/security/identity-protection/hello-for-business/hello-features#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.| 1809 |

|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.| 1809 |
|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](https://blogs.windows.com/windowsexperience/2018/05/03/announcing-windows-10-insider-preview-build-17661/#8xbvP8vMO0lF20AM.97), 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.| 1809 |
|[Software Restriction Policies](https://docs.microsoft.com/windows-server/identity/software-restriction-policies/software-restriction-policies) in Group Policy|Instead of using the Software Restriction Policies through Group Policy, you can use [AppLocker](https://docs.microsoft.com/windows/security/threat-protection/applocker/applocker-overview) or [Windows Defender Application Control](https://docs.microsoft.com/windows/security/threat-protection/windows-defender-application-control) to control which apps users can access and what code can run in the kernel.| 1803 |

|Windows Help Viewer (WinHlp32.exe)|All Windows help information is [available online](https://support.microsoft.com/products/windows?os=windows-10). The Windows Help Viewer is no longer supported in Windows 10. If for any reason you see an error message about "help not supported," possibly when using a non-Microsoft application, read [this support article](https://support.microsoft.com/help/917607/error-opening-help-in-windows-based-programs-feature-not-included-or-h) for additional information and any next steps.| 1803 |
|MBAE service metadata|The MBAE app experience is replaced by an MO UWP app. For more information, see [Developer guide for creating service metadata](https://docs.microsoft.com/windows-hardware/drivers/mobilebroadband/developer-guide-for-creating-service-metadata) | 1803 |
|Contacts feature in File Explorer|We're no longer developing the Contacts feature or the corresponding [Windows Contacts API](https://msdn.microsoft.com/library/ff800913.aspx). Instead, you can use the People app in Windows 10 to maintain your contacts.| 1803 |
|Phone Companion|Use the **Phone** page in the Settings app. In Windows 10, version 1709, we added the new **Phone** page to help you sync your mobile phone with your PC. It includes all the Phone Companion features.| 1803 |

**Applies to**
- Windows 10, version 20H2
This article lists new and updated features and content that is of interest to IT Pros for Windows 10, version 20H2, also known as the Windows 10 October 2020 Update. This update also contains all features and fixes included in previous cumulative updates to Windows 10, version 2004.
> [!NOTE]
> With this release and future releases, the Windows 10 release nomenclature is changing from a year and month pattern (YYMM) to a year and half-year pattern (YYH1, YYH2).
As with previous fall releases, Windows 10, version 20H2 is a scoped set of features for select performance improvements, enterprise features, and quality enhancements. As a [September-targeted release](https://support.microsoft.com/help/13853/windows-lifecycle-fact-sheet), 20H2 is serviced for 30 months from the release date for devices running Windows 10 Enterprise or Windows 10 Education editions.
To download and install Windows 10, version 20H2, use Windows Update (**Settings > Update & Security > Windows Update**).
## Microsoft Edge
This release automatically includes the new Chromium-based [Microsoft Edge](https://www.microsoft.com/edge/business) browser instead of the legacy version of Edge. For more information, see the [Microsoft Edge documentation](https://docs.microsoft.com/microsoft-edge/).
## Servicing
### Windows Update
There are several changes that help improve the security of devices that scan Windows Server Update Services (WSUS) for updates. For more information, see [Changes to improve security for Windows devices scanning WSUS](https://techcommunity.microsoft.com/t5/windows-it-pro-blog/changes-to-improve-security-for-windows-devices-scanning-wsus/ba-p/1645547).

New guidance is available to help prepare a [servicing strategy](https://docs.microsoft.com/windows/deployment/update/waas-servicing-strategy-windows-10-updates) and move your devices to the latest version of Windows 10 quickly and as seamlessly as possible.
These steps have been broken into the following phases: **Plan** > **Prepare** > **Deploy**:
**Plan** your deployment by evaluating and understanding essential activities:
- Create a [phased deployment plan](https://docs.microsoft.com/windows/deployment/update/create-deployment-plan)
- Assign [roles and responsibilities](https://docs.microsoft.com/windows/deployment/update/plan-define-readiness#process-manager) within your organization

- Use [Windows Update for Business](https://docs.microsoft.com/windows/deployment/update/waas-configure-wufb) and [customize update settings](https://docs.microsoft.com/windows/deployment/update/waas-wufb-group-policy) for your devices
- Use Windows Server Update Services (WSUS) to [deploy Windows updates](https://docs.microsoft.com/windows/deployment/update/waas-manage-updates-wsus)
- Use [Delivery Optimization](https://docs.microsoft.com/windows/deployment/update/waas-delivery-optimization) to manage bandwidth for updates
