Hi everyone,

If Adobe Acrobat is displaying your login name as the author of comments and you want to change the name shown on your annotations, see the consolidated annotation and commenting guide below. It covers the Always use Log-in Name for Author name preference, changing the comment author name, and setting the preferred author name for new comments.

I do have the same problem described in this post: the Author name I want to use is different from the login name (which I really don't know where it came from, by the way). The option "Always use login name etc" is ticked off, I changed the default options for Author Comment on one of the notes, restarted several times, but...

 

Login name still appear on the comments.

What could I do?

 

Any help will be truly appreciated.

I managed to get the "Login name" to change by following the instructions here: https://superuser.com/questions/371382/where-is-username-variable-defined

Specifically this:

  • Use lusrmgr.msc to modify the user name by clicking it, pressing F2 and changing it (then log out/in or reboot).

This does not work anymore in recent Windows version. Run netplwiz instead.

The login-name is fixed. You can change the author name, though.

Go to Edit - Preferences - Commenting and make sure that "Always use log-in name for author name" is ticked off, and then select your comment, right-click it and select Properties. You'll be able to change the Author name in that window.

Afterwards you can right-click it again and select to use the current value as the new default.

I appreciate your quick feedback ... and the (effective) workaround. Do you know why on Earth Adobe decided to lock the login name itself? What does that accomplish, except to irritate the heck out of people?

It's locked because it's a value that comes from the operating system, and Acrobat can't change it. It's the name of the currently logged-in user on the machine.
