Powerpoint / 'Insert Comment': change reviewer name

[Cardi2701]

How can I change the automatically appearing name in the Comment box when I
insert a Comment in a Powerpoint presentation (my sister once borrowed my
computer and obviously did a PP presentation, using her name when she
inserted a comment. Therefore, HER name now shows up automatically as author
of a Comment, when I really want MY name to show up. N.B. I had never used
Powerpoint before, so didn't notice this until recently... Thanks!

Always good to mention which version you use.

If it's 2007 try:
Office button (big & round)
PowerPoint Options (small and rectangular)
Popular >Personalize your copy

Earlier try:
Tool > Options >General
