Few Changes: Focus on quality and reliability improvements Few Changes: Most software that runs on Windows Vista will run on Windows 7 - exceptions will be low level code (AV, Firewall, Imaging, etc). Hardware that runs Windows Vista well will run Windows 7. Deep Changes: New models for security, drivers, deployment, and networking

Notes (hidden) Some speakers at Microsoft like to use this slide for hidden “notes slides”. Delete it if you don’t want to use it. NEXT:

Font, size, and color for text have been formatted for you in the Slide Master Use the color palette shown below See next slide for additional guidelines Hyperlink color: Sample Fill

Example of a slide with a subhead Set the slide title in “title case” Set subheads in “sentence case” Generally set subhead to 36pt or smaller so it will fit on a single line The subhead color is defined for this template but must be selected; In PowerPoint 2007, it is the fourth font color from the left

Use this layout to show software code The font is Courier, a monospace font The slide doesn’t use bullets but levels can be indented using the “Increase List Level” icon on the Home menu
