We have a lab with many different users. Word 2010 defaults to Calibri. They want all users to have a default of Times New Roman. Is this possible?
Yes, it's possible and fairly easy.
Find and open the normal.dotm template (users\username\appdata\roaming\microsoft\templates), change the font to your desired font and size and save it.
Distribute it to the user machines.
Every new document will open with this template and the font will default to what you set it as.
After modify the file normal.dot to use your desired font, you can also create a Windows Script to copy this file to the users folder, so you won´t need to copy manually this file.
