Actually, my method of toggling the read-only attribute of Word.qat requires two macros. One switches on the read-only attribute of Word.qat to prevent it from being changed. The other clears the read-only attribute so buttons can be added or removed.

Just add these macros as buttons to the QAT to quickly protect and unprotect it. I prefer two buttons to a single button because I don’t know of a way of telling, visually, the current state of the read-only attribute of a file. I’d love to change the appearance of the button to indicate the state, but I haven’t found a way to do this. So for now, two buttons allow the user to take exactly the action desired.

Why would you ever need to do this?

Buttons disappearing from the QAT is a pretty common occurrence.

If your Quick Access Toolbar contains buttons from templates or COM add-ins, these custom buttons can be lost when Word is closed and reopened. To demonstrate this, add such a button to the QAT, then close Word and reopen it from the command line with winword.exe /a (the /n switch may also demonstrate this). Word will open, but without any add-ins. Instead of creating a temporary Word.qat with the default buttons, the working Word.qat file is edited to remove all the non-native Word buttons. The appearance to the user is that Word loses the custom buttons. Once the buttons disappear, they do not return when Word is opened normally.

From what I can tell, the QAT buttons disappearing isn’t a random event or a bug, but an intentional consequence of initiating a Word instance without any add-ins or a result of a badly written function in a template or add-in.
