Where are changes to macros and toolbars stored in Word 2010?

There are no user configurable toolbars in Word 2007 or Word 2010!
See Toolbars and Word 2007/2010

Normal.dotm is a default holder for macros, keyboard customizations, formatted AutoCorrect, and AutoText.
You can store these (except the AutoCorrect) in other templates instead. Those templates can be loaded as global templates sharing their resources with all other documents. See Templates in Microsoft Word

Transferring all AutoCorrect requires the use of a special utility. See the article "What files do I need to back up?” at:

http://word.mvps.org/FAQs/General/FilesToBackup.htm

It has links to the article "How can I import and export all my AutoCorrect entries, so they can be transferred to another machine?” at:

http://word.mvps.org/FAQs/Customization/ExportAutocorrect.htm. See also AutoCorrect2007.zip The AutoCorrect backup/restore template updated for use with Word 2007 and Word 2010.

and to the article "What do Templates and Add-ins store?” at:

http://word.mvps.org/FAQs/Customization/WhatTemplatesStore.htm

In Word 2010 you can customize the Ribbon and the QAT (quick action toolbar) through the interface. You can export these settings and import them on another system. Doing so erases any RIbbon/QAT customizations that were on that other system before the import.

You can confine ribbon and QAT settings to a single template rather than the entire system by modifying the XML of the template. This would allow you to copy customizations to another computer without overwriting those already there. It is more work. Customize the Ribbon (It doesn't take rocket science)

2007 and 2010 also have very different defaults saved in the NORMAL.DOTM than 2003 and earlier. MS has changed the default font and spacing and a bunch of other "stuff".

If you want to continue using your 2003 look and feel, you can import those settings into 2010.  Close all Word instances (including Outlook). Find your personal NORMAL.DOTM and rename or delete it. Copy your 2003 NORMAL.DOT into the same folder. Next time you start Word, it will see that there is no NORMAL.DOTM so it will regenerate it. But rather than using the hard coded defaults, since it sees your old NORMAL.DOT, it will copy setting from that.

This tip tells you how to copy Ribbon customization from one machine to another:

Although you can't create toolsbars in the Ribbon "gooey", you still can import them from 2003:

This group of tools will help you get comfortable with the Ribbon faster

A key point to keep in mind is that from the point of view of the "Average User", Office 2007 and 2010 are 99% identical. Tips specific to 2007 almost always are still valid in 2010 apps so don't automatically ignore things that were created for 2007.

Office Watch Word Command Finder -

The Office watch Word command finder is really good tool, it actually provides a more focused result, but the path it describes is sometimes wrong. (They got all of the info from MS ...). They have also added some commands that are not on the “official” MS command list.

You can add the link to OWW Command Finder tool to the QAT using this macro:

Stop Clicking and Exploring Excel 2007 like a Newbie - http://www.scribd.com/doc/29093109/Stop-Clicking-Exploring-Excel-Ribbon-Like-Newbie - applies to any Ribbonized app. This is an excellent booklet to get people into the right frame of mind to learn and use the ribbonized apps.

 

I just watched the video on this page:

http://blogs.msdn.com/b/jensenh/archive/2008/03/12/the-story-of-the-ribbon.aspx

It's just under 1.5 hours. I found it quite informative. It explains a lot of the (ir)rational behind the Ribbon design, including the name by the Manager in charge of it's development (not that I agree with it all...).  The slides download just don't tell the story.

Here are some general infomation links:
