Known issues in this update

Symptom	Workaround
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-based computer, 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 do not work correctly. Webpages intermittently do not load or render correctly. Issues affect credential notifications. Issues occur when downloading files.	This issue is resolved in KB4493472.
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 KB4493472.
After installing this update, NETDOM.EXE fails to run, and the on-screen error, “The command failed to complete successfully.” appears.	This issue is resolved in KB4493472.
After installing this update, some customers report that authentication fails for services that require unconstrained delegation after the Kerberos ticket expires (the default is 10 hours). For example, the SQL server service fails.	This issue is resolved in KB4499164.
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 KB4493472.
