If you have already used Maya or have a prior version of Maya installed, you should restore the default settings for Maya before you begin the lessons. This ensures that Maya appears and operates exactly as the lessons describe.
If you are an existing user of Maya we recommend that you save your existing preferences for later use prior to restoring the default user settings.
To save your existing custom user preferences
Each time you exit Maya it saves the configuration of most components of your user interface so it appears the same when you start it the next time. It writes the preferences to a directory called prefs. If you rename the prefs directory, your original preferences will be maintained and Maya will create a new prefs directory the next time it is run.
\Documents and Settings\<username>\My Documents\maya\ 2009\en_US\prefs
\Documents and Settings\<username>\My Documents\maya\ 2009-x64\en_US\prefs
\Users\<username>\Documents\maya\2009\en_US\prefs
\Users\<username>\Documents\maya\2009-x64\en_US\prefs
/Users/<username>/Library/Preferences/Autodesk/maya/en_US/2009/prefs
~<username>/maya/2009-x64/en_US/prefs
If you have a previous version of Maya installed, also rename that prefs directory to a new name such as myprefs. Maya will load older preferences if they exist from a previous version.
