First method: Modify the name of the template file "Normal.dot"
A, to find the Normal.dot file first, because it is hidden, the following method:
Open My computer → tools → folder options → Check the check box before "Hide protected operating system files" and "Show All Files and folders" in view.
B, open the C:documents and Settingsadministratorapplication datamicrosofttemplates folder, and change the name of the "Normal.dot" file at random.
After Word starts, it rebuilds the Normal.dot because Normal.dot does not exist, restoring Word's initial settings, and of course the menu bar appears again.
Of course, you can not change the name of the Normal.dot, but directly delete it also.
Second method: Restore through Registry
Click the Start menu → run to enter "regedit" and then go to Registry Editor
Expand Hkey_current_usersoftwaremicrosoftoffice11.0word to remove the word registry, which holds the key values for some of the settings in Word 2003 and the registration information for some plug-ins, When you delete and then reopen word, Word automatically installs the default initial key value and the menu bar is restored.
Knowledge Extension:
If not, then reinstall Word. There is no way, simply reinstalling Office is also possible. Of course, in general, using the first method will solve your problem.
