| Global DNS outage affects Windows Update customers Windows Update customers were affected by a network infrastructure event on January 29, 2019 (21:00 UTC), caused by an external DNS service provider's global outage. A software update to the external provider's DNS servers resulted in the distribution of corrupted DNS records that affected connectivity to the Windows Update service. The DNS records were restored by January 30, 2019 (00:10 UTC), and the majority of local Internet Service Providers (ISP) have refreshed their DNS servers and customer services have been restored. Affected platforms:
While this was not an issue with Microsoft's services, we take any service disruption for our customers seriously. We will work with partners to better understand this so we can provide higher quality service in the future even across diverse global network providers. If you are still unable to connect to Windows Update services due to this problem, please contact your local ISP or network administrator. You can also refer to our new KB4493784 for more information to determine if your network is affected, and to provide your local ISP or network administrator with additional information to assist you.

| Issue using PXE to start a device from WDS After installing KB4489868, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension. Affected platforms:
Workaround: To mitigate the issue, disable the Variable Window Extension on WDS server using one of the following options: Option 1: Open an Administrator Command prompt and type the following: Wdsutil /Set-TransportServer /EnableTftpVariableWindowExtension:No - Option 2: Use the Windows Deployment Services UI to make the following adjustment:
Option 3: Set the following registry value to 0: HKLM\\System\\CurrentControlSet\\Services\\WDSServer\\Providers\\WDSTFTP\\EnableVariableWindowExtension Restart the WDSServer service after disabling the Variable Window Extension.
