Applies to: Excel 2016


This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see Microsoft Security Bulletin MS16-042.

Note To apply this security update, you must have the release version of Excel 2016 installed on the computer.

For a complete list of affected versions of Microsoft Office software, see Microsoft Knowledge Base article KB3148775.

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:
  • When you open many workbooks in Excel 2016, device context leaks.
  • Some object model calls (Range::HasArray, Range:HasFormula and Range::NumberFormat) are slower in Excel 2016 compared to earlier versions of Excel.
  • It takes a long time to filter large tables in Excel 2016.
  • When you use the Sampling analysis tool of Analysis Toolpak and use 13 as the number of samples in Excel 2016, Excel 2016 crashes.
  • When you try to close a workbook that's opened by a modal userform, the workbook that contains the macro and the userform is closed unexpectedly.
  • After you paste a range that contains a data table from one instance of Excel into another, the values from the data table are pasted into the correct destination range, but the data table is also pasted into the original location of the sheet.
