I am using Windows 8.1 and Office 2007. When I want to save a document and the 'save as' box comes up there is no option to save on the desktop by default. I have to go to windows c>users> desktop etc.. to save it. A bit long winded wouldn't you agree? What can I do about this please? Thanks.
"... the 'save as' box comes up there is no option to save on the desktop by default."
It should be there amongst the other locations in the left-pane of the Save As box. It's normally part of the "Favorites" section. If you still can't see then it may be hiding from you so click on Favorites to expand the list.
Alternatively, click on the far left-hand arrow in the Address Bar at the top and Desktop should appear in the drop-down list.
OK - right-click on Favorites and choose "Restore Favorite Links". Or you could navigate to the Desktop like you've been doing then right-click on Favorites and choose "Add current location to Favorites".
