Known issues in this update

Symptom	Workaround
For hosts managed by System Center Virtual Machine Manager (SCVMM), SCVMM cannot enumerate and manage logical switches deployed on the host after installing the update. Additionally, if you do not follow the best practices, a stop error may occur in vfpext.sys on the hosts.	This issue is resolved in KB4507459.
After installing KB4467684, the cluster service may fail to start with the error “2245 (NERR_PasswordTooShort)” if the group policy “Minimum Password Length” is configured with greater than 14 characters.	Set the domain default "Minimum Password Length" policy to less than or equal to 14 characters. Microsoft is working on a resolution and will provide an update in an upcoming release.
After installing this update, Internet Explorer 11 and other applications that use WININET.DLL may have authentication issues. This occurs when two or more people use the same user account for multiple, concurrent login sessions on the same Windows Server machine, including Remote Desktop Protocol (RDP) and Terminal Server logons. Symptoms reported by customers include, but may not be limited to: Cache size and location show zero or empty. Keyboard shortcuts may not work properly. Webpages may intermittently fail to load or render correctly. Issues with credential prompts. Issues when downloading files.	This issue is resolved in KB4493470.
After installing this update, MSXML6 causes applications to stop responding if an exception was thrown during node operations, such as appendChild(), insertBefore(), and moveNode(). The Group Policy editor may stop responding when editing a Group Policy Object (GPO) that contains Group Policy Preferences (GPP) for Internet Explorer 10 settings.	This issue is resolved in KB4493470.
After installing this update, Custom URI Schemes for Application Protocol handlers may not start the corresponding application for local intranet and trusted sites on Internet Explorer.	This issue is resolved in KB4493473.
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.	This issue is resolved in KB4503267.
If you enable per font end-user-defined characters (EUDC), the system will stop working and a blue screen will appear at startup. This is not a common setting in non-Asian regions.	This issue is resolved in KB4493470.
Any compound document (OLE) server application that places embedded objects into the Windows Metafile (WMF) using the PatBlt API may display embedded objects incorrectly. For example, if you paste a Microsoft Excel worksheet object into a Microsoft Word document, the cells may render with a different background color.	This issue is resolved in KB4493470.
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.
