A family of Microsoft word processing software products for creating web, email, and print documents.
Setting "All Markup" as the default for all documents should be easy: just change the setting and it stays that way.
There have been reports in the forum suggesting that this doesn't always work, though. If that happens, try the following: Make sure that only one document is open. Change to "All Markup," close the document and exit Word. Restart and verify that the option sticks.
If it still doesn't work, post back, as you may need a macro to force "All Markup."
