Either right click in the menu area or select "Toolbars" in the View menu to
display the toolbar menu. Select "Customize." Now in the menu choose
"Help," click and drag the "Detect and Repair" entry out of the toolbar
zone. This is the standard procedure in all MS Office products for
customizing toolbars and menus. OF course, that won't stop a knowledgable
user from opening the Customize dialog themselves and hitting the Reset
button to restore the menu to the "As Shipped" version.
Now that that is said, why in the world you want to? That's there so the
user can repair those little glitches to pop in from time to time. IMHO,
there's no valid reason for not letting your users have that ability. I'm
getting more than a little preturbed at the current trends to try to turn
people's lives into a series of black boxes where all they're allowed to do
is push the buttons that their superiors tell them to, when their superiors
tell them to. If you're rolling out manager's tool like MS Project to your
users, surely they have the smarts to use features like "Detect and
Repair..." appropriately. Far better to set it up so they have network
access to the install image and educate them in the proper use of the tool
than take away an important tool they might urgently need someday when
something goes wrong, they're up against a deadline and you're not available
to make a service call.
