Is there an easy way to restrict the PowerPoint I want to have in the Content area so the information can't be changed?

In this case, the best way to post PowerPoint files is as a PDF document. Your students will be able to view the slides and print them but not be able to make changes to them. It will also take less time for the students to download the file. See an example of this.

Here's how to do this:

  1. In PowerPoint 2013 (PC), from the File tab, select Print. In PowerPoint 2008 (Mac), select File -> Print.
  2. PC - from the Printer drop-down menu, select Adobe PDF. Mac - from the PDF button select Save as PDF.
  3. PC - from the Settings area, select the Layout drop-down menu, select Handouts option you would like to use. Mac - from the Print What drop-down menu, select Handouts
  4. PC - click Print. The Save PDF File As dialog box will appear.
  5. PC & Mac - name the PDF file and click Save.
