Powerpoint 2010: Remove all notes from slides at once
1. Open your Powerpoint document.
2. Go to File->Check for Issues->Inspect document.

3. A new window will pop up and ask if you want to save your document. Because our main aim is just to remove all notes, saving a document is may not necessary at this part, so we can choose No.

4. In Document Inspector window, check on Presentation Notes and hit Inspect.

5. If the Document Inspector found any notes, it will notice you like below. Just choose Remove all to remove all notes and hit Close.

6. You can now save your document. Just click on Save button or press Ctrl+S
