How could the sub below be generalized to work on all simultaneously open
books and views (I may have some books open with multiple windows)? The sub
currently works only on the activebook/view (where the cursor is). Thanks

Sub NoGridLinesZoom75()
Dim ws As Worksheet
Dim wsht As Worksheet
Set wsht = ActiveSheet
For Each ws In ActiveWorkbook.Worksheets
ws.Activate
ActiveWindow.DisplayGridlines = False
ActiveWindow.Zoom = 75
Next
wsht.Select
End Sub
