Description
When users create new document files, Word 2010 saves them in the new Word 2010 .docx format. Ensure this setting is enabled to specify that all new files are created in Word 2010. If a new document is created in an earlier format, some users may not be able to open or use the file, or they may choose a format this is less secure than the Word 2010 format. Users can still select a specific format when they save files, but they cannot change default of this setting from the Word Options dialog box. This enforced user behavior ensures any change to the file format requires additional deliberate user interaction.
