Known issues in this update

Symptom

Workaround

After installing KB4493509, devices with some Asian language packs installed may receive the error, "0x800f0982 - PSFX_E_MATCHING_COMPONENT_NOT_FOUND."

This issue is addressed by updates released June 11, 2019 and later. We recommend you install the latest security updates for your device. Customers installing Windows Server 2019 using media should install the latest Servicing Stack Update (SSU) before installing the language pack or other optional components. If using the Volume Licensing Service Center (VLSC), acquire the latest Windows Server 2019 media available. The proper order of installation is as follows:

  1. Install the latest prerequisite SSU, currently KB5005112

  2. Install optional components or language packs

  3. Install latest cumulative update

Note Updating your device will prevent this issue, but will have no effect on devices already affected by this issue. If this issue is present in your device, you will need to use the workaround steps to repair it.

Workaround:

  1. Uninstall and reinstall any recently added language packs. For instructions, see Manage the input and display language settings in Windows 10.

  2. Click Check for Updates and install the April 2019 Cumulative Update or later. For instructions, see Update Windows 10.

Note If reinstalling the language pack does not mitigate the issue, use the In-Place-Upgrade feature. For guidance, see How to do an in-place upgrade on Windows, and Perform an in-place upgrade of Windows Server.

When using Windows Server containers with the March 10, 2020 updates, you might encounter issues with 32-bit applications and processes.

For important guidance on updating Windows containers, please see Windows container version compatibility and Update Windows Server containers.

Devices using a manual or auto-configured proxy, especially with a virtual private network (VPN), might show limited or no internet connection status in the Network Connectivity Status Indicator (NCSI) in the notification area. This might happen when connected to or disconnected from a VPN or after changing the state between the two. Devices with this issue might also have issues reaching the internet using applications that use WinHTTP or WinInet. Examples of apps that might be affected on devices in this state include, but are not limited to, Microsoft Teams, Microsoft Office, Microsoft Office 365, Microsoft Outlook, Internet Explorer 11, and some versions of Microsoft Edge.

This issue is resolved in KB4554354.

Devices on a domain might be unable to install apps published using a Group Policy Object (GPO). This issue only affects app installations that use .msi files. It does not affect any other installation methods, such as from the Microsoft Store.

This issue is resolved in KB4549949.

How to get this update
