    license.SetLicense(@"D:\GroupDocs.Watermark.lic");

    using (var doc = Document.Load<SlidesDocument>(@"D:\test.pptx"))
    {
        foreach (var slide in doc.Slides)
        {
            string oldUrl = "http://aspose.com/";

            // Assign null to remove hyperlink
            string newUrl = "http://groupdocs.com/";

            // Replace hyperlinks in shapes
            foreach (var shape in slide.Shapes)
            {
                ReplaceHyperlink(shape, SlidesHyperlinkActionType.MouseOver, oldUrl, newUrl);
                ReplaceHyperlink(shape, SlidesHyperlinkActionType.MouseClick, oldUrl, newUrl);

                // Replace hyperlinks in text fragments
                foreach (var fragment in shape.FormattedTextFragments)
                {
                    ReplaceHyperlink((ISlidesHyperlinkContainer)fragment, SlidesHyperlinkActionType.MouseClick, oldUrl, newUrl);
                    ReplaceHyperlink((ISlidesHyperlinkContainer)fragment, SlidesHyperlinkActionType.MouseOver, oldUrl, newUrl);
                }
            }

            // Replace hyperlinks in charts
            foreach (var chart in slide.Charts)
            {
                ReplaceHyperlink(chart, SlidesHyperlinkActionType.MouseOver, oldUrl, newUrl);
                ReplaceHyperlink(chart, SlidesHyperlinkActionType.MouseClick, oldUrl, newUrl);
            }
        }

        // Save changes
        doc.Save();
    }
}

private static void ReplaceHyperlink(ISlidesHyperlinkContainer hyperlinkContainer, SlidesHyperlinkActionType hyperlinkActionType, string oldUrl, string newUrl)
{
    if (hyperlinkContainer.GetHyperlink(hyperlinkActionType) == oldUrl)
    {
        hyperlinkContainer.SetHyperlink(hyperlinkActionType, newUrl);
    }
}

using (var doc = Document.Load(@"D:\test.pptx"))
{
    doc.SearchableObjects.SlidesSearchableObjects = SlidesSearchableObjects.Hyperlinks;

    // Find all hyperlinks
    var watermarks = doc.FindWatermarks();

    // Remove found watermarks
    watermarks.Clear();

    // Save changes
    doc.Save();
}
