Use non-editable Headers and footers in PPT 2007-2010 like in previous versions

Headers and footers PPT 2007 immovable, uneditable in your slides? 

Headers and footers behave differently from PPT 2003 as I reported a while back. If you still want immovable or undeletable footers you will have to insert them yourself. Here's how:

On the master and the slide layouts delete the footer and numbering placeholder.

Put two regular textboxes as a replacement. Type in the footer text in one of them, in the other insert the slide number using Insert tab, Slide number button in the Text group.

Change the formatting to fit your needs.

Both textboxes will act as footer and slide number and will not be editable in your slides just like in previous versions of PowerPoint.

If you had already applied a slide number or footer remove them first before you start the procedure. Use the Header and footer button and in the dialog, be sure to uncheck them and Apply to all.
