Applications that use a Microsoft Jet database with the Microsoft Access 97 file format may fail to open if the database has column names greater than 32 characters. The database will fail to open with the error, “Unrecognized Database Format”.

This issue is resolved in KB4486996.

After installing KB4480978, some Microsoft Edge users report that they:

  • Cannot load webpages using a local IP address.

  • Cannot load webpages on the Internet using a VPN connection.

This issue is resolved in KB4486996.

After installing this update, the first character of the Japanese era name is not recognized as an abbreviation and may cause date parsing issues.

This issue is resolved in KB4487021.

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 KB4493441.

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.
