Remove Excel task from Task manager after running from Access using VBA

Solution 1:

In the comments you mentioned that you had reset your code (i.e. pressed the stop button). This means that the portion of your code that kills excel did not run, thus leaving an open session of excel. There is a small (possibly semantic) issue with your code, but I don't believe that's what was causing your issue. Regardless, you should properly shut down the application like this.

ExitSub:
    If Not objWorksheet Is Nothing Then
        set objWorksheet = Nothing
    End If
    ' You have to check for the workbook's existence before 
    '    you try to close something that isn't there. This avoids runtime errors.
    '    Since your error handler points you back here, this code always runs, so
    '    The workbook might not be open.
    If Not objWorkbook Is Nothing Then
        objWorkbook.close
        Set objWorkbook = Nothing
    End If
    ' Same goes for quitting the application
    If Not objExcel Is Nothing Then
        objExcel.Quit
        Set objExcel = Nothing
    End If

    Exit Sub
Error_Handler:
    ' error handling code here
     Resume ExitSub
End Sub

Solution 2:

Columns("A:F").EntireColumn.AutoFit

Adding as an answer just in case. Fully qualify this with the worksheet name and try again. This same problem was a huge bother to me too. You have to qualify 100% of your references, no matter what. Also, be super careful about using With statements on ranges, worksheets etc. So change it to ObjWorksheet.Columns("A:F")... instead
