Protecting a Whole Workbook
You can also protect an entire workbook—but doing so brings about a result you’re not likely to expect.

prevents the user from making what Excel calls structural changes in the book—that is, adding moving,
renaming, or deleting worksheets. It will also allow you to protect against changes to current window
sizes, meaning if you accept this option and your worksheet currently occupies less than a whole
screen’s worth of space, you won’t be able to restore it to full size via the Maximize button, for example.
