  • Addressed issue with form submissions in Internet Explorer.

  • Addressed issue where messages that should be in a non-English language display in English in Internet Explorer.

  • Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.

Known issues in this update


Symptom Workaround

Installing this update may cause applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) to fail when creating or opening Microsoft Excel .xls files. The error message is, “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

Download and install the Microsoft Access Database Engine 2010 Redistributable, and then modify the DB connection strings in Microsoft Excel to use ACE as a provider. Example: Change Provider=Microsoft.Jet.OLEDB.4.0 to Provider=Microsoft.ACE.OLEDB.12.0.

Microsoft is working on a resolution and will provide an update in an upcoming release.

Some users who have the text size for icons set to a larger size (using Display Settings in Control Panel) may have issues launching Internet Explorer.

Reducing the text size for icons to a smaller value or using the Change the size of all items setting should alleviate this issue.

Microsoft is working on a resolution and will provide an update in an upcoming release.
