When your PowerPoint presentation is digitally signed and shared, it helps to validate your identity. However, at times you may want to remove a digital signature attached to your PowerPoint presentation for several reasons, you may want it to be signed by someone else, or maybe there's no need for a particular presentation to be signed anymore. A digital signature can be easily removed from your presentation.
Follow these steps to remove the digital signature from a PowerPoint presentation in PowerPoint 2010 for Windows:
- Open the presentation that is digitally signed in PowerPoint. Note that the open presentation will contain a yellow strip in the area below the Ribbon and above the Slide Area, as shown in Figure 1, below. The yellow strip indicates that this presentation is attributed read-only to discourage modifications. Note that the text message in the yellow strip reads Marked as Final, this is the same as the Mark as Final option we explored in a previous tutorial.
Figure 1: Presentation with a yellow strip above Slide Area- Click the Edit Anyway button, as shown highlighted in red within Figure 1, above, within the yellow strip. Doing so brings up the Microsoft PowerPoint window, as shown in Figure 2, below. Within this window, click the Yes button to remove the signature in this presentation and enable further editing.
