If you want that zoom for just new workbooks, you can ignore this. But if you
want that zoom whenever you open any workbook....

Create a new workbook.
Add this code to the ThisWorkbook module (hi, Bob!):

Option Explicit
Public WithEvents xlApp As Application
Private Sub Workbook_BeforeClose(Cancel As Boolean)
Set xlApp = Nothing
End Sub
Private Sub Workbook_Open()
Set xlApp = Excel.Application
End Sub
Private Sub xlApp_NewWorkbook(ByVal Wb As Workbook)
Call DoTheWork(Wb)
End Sub
Private Sub xlApp_SheetActivate(ByVal Sh As Object)
Call DoTheWork(Sh.Parent)
End Sub
Private Sub xlApp_WorkbookOpen(ByVal Wb As Workbook)
Call DoTheWork(Wb)
End Sub
Private Sub DoTheWork(Wb As Workbook)
Dim myWindow As Window
For Each myWindow In Wb.Windows
myWindow.Zoom = 75
Next myWindow
End Sub

Save this file as an addin in your XLStart folder.

Each time you create a new workbook, open an existing workbook, change to a new
sheet, it'll set the zoom to 75%.

If you're new to macros, you may want to read David McRitchie's intro at:

Hi
I want to set the default view of excel to 75% . When ever I open Excel or a
new file in Excel the view should be 75% by default.
