A local (not active directory) user account has been changed. This may be a password reset, or may be any attribute of the account being changed (eg the Full Name or Description).

The changes will be somewhere in the description and the eventdata, but note that not everything that appears to have changed actually has done. For example - the above sample is from a password reset, using the lusrmgr.msc mmc snap-in, but this also seems to result changes to (among other things) the home folder, password expiry and logon hours, even though only the password (and therefore the password last set attribute) has been changed. This behaviour is the same when using net user [username] Pa55w0rd! to set the password.

The "subject" account is the one which has made the change. The "target" account is the one to which the change was made.
