Known issues in this update

Symptom	Workaround
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 KB4493475.
After installing this security 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 KB4493475.
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 KB4493475.
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.
