Windows
 

If you protect the workbook (not the worksheet), then the minimize and
maximize icons are removed from the workbook menu. This still allows the
application to be minimized (I am not sure which action causes the menu to
be reset).

If you need to do this to the Application window (Excel), you have to use
the windows API:

the first two show you how. The second two just provide some useful
information about working with windows and using the API.

Is there a code to prevent users from minimising windows
on an excel spreadsheet by clicking on the taskbar- the
problem is that it opens again with a different set of
toolbars. Thanks.
