Symptom	Workaround
After installing this update, 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.	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. Open Windows Deployment Services from Windows Administrative Tools. Expand Servers and right-click a WDS server. Open its properties and clear the Enable Variable Window Extension box on the TFTP tab. 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. Microsoft is working on a resolution and will provide an update in an upcoming release.
Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.	Do one of the following: Perform the operation from a process that has administrator privilege. Perform the operation from a node that doesn’t have CSV ownership. Microsoft is working on a resolution and will provide an update in an upcoming release.

Microsoft is preparing for the release of version 1903

With the May 2019 Update slated to be released this month, Microsoft has released KB4497092 which is titled "Compatibility update for upgrading to Windows 10, Version 1903: May 1, 2019".

This update makes changes to the Windows Update experience so that the Windows 10 May 2019 Update will install without problems.

Last week, Microsoft stated that version 1903 would be blocked from being installed if the machine has an attached USB drive or SD Card.  This was because USB drives or SD cards could have their drive letters reassigned in a way that could cause a conflict.

Microsoft stated they would be releasing a Windows 10 service update to resolve this issue. It is not known if this update is the one that resolves this issue.
