Using Excel 2013. If you go to the very last picture of this other forum this is basically what I'm trying to accomplish. However when I close the work book and go back in it revert back. I've tried logging in with an administrator domain account with same results. Has any experienced this?

From 4 to 1.  I even tried un-checking Enable multi-threaded calculation and it greys out everything but next time I go back in it has it checked and using all processors.

I've been able to reproduce the behavior. I'm reaching out to Microsoft and the Microsoft MVPs to see if anyone else can shed any light on this.

Some additional discovery:

- This is not a problem in 2010.

- If I use 2013 to open a workbook created in 2010 then any changes to these settings made in 2013 do seem to stick.

I've figured it out. The settings behave the same way that the Calculation mode setting behaves. It's a little convoluted but does make sense.

The calculation mode option is set and stored with the workbook but exactly how that happens is not always the most logical. And it is ignored when opening a workbook into an existing Excel instance with one or more workbooks already open. Every Excel application instance starts with the calculation mode set as defined in the first workbook opened. All other workbooks opened assume the currently set calculation mode.

So, to use the threading settings, you have to ensure that the workbook with the desired settings is opened before any other workbook.

The reason I was not able to reproduce the "problem" in 2010 is that, as my system is configured, I was always opening the workbook with the custom threading settings before any other workbook. In 2013 I was not.

You can force Excel to use one processor whenever your workbook is opened regardless of what other workbooks are open by putting this VBA code in the ThisWorkbook code module:

Private Sub Workbook_Open()
    Application.MultiThreadedCalculation.ThreadCount = 1
End Sub
