Remove Digital Signatures in PowerPoint 2010 for Windows

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 to for a particular presentation to be signed any more. A digital signature can be easily removed from your presentation. Follow these steps to remove the digital signature from a PowerPoint presentation:

1. Open the presentation that is digitally signed in PowerPoint 2010. 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. 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.

2. Click the Edit Anyway button (highlighted in red in Figure 1, above) within the yellow strip. This brings up the Microsoft PowerPoint window, as shown in Figure 2. Within this window, click the Yes button to remove the signature in this presentation and to enable editing.

Click the downward arrow to bring up a drop-down list, from this drop-down list, select the Remove Signature option (highlighted in red in Figure 6).
