a. ok now, what you need to do is to:
>> run compmgmt.msc b. and >>click on local
>> users and groups.
>> Open 'users' folder.
>> Double Click On the user of your choice

The Form Should Have:
<Label> "user name"

full name: <textbox>

description: <Textbox>

<Checkbox> user must change password at next logon

<Checkbox> user cannot change password

<Checkbox>(Checked) password never expires

<Checkbox> account is disabled

<Checkbox> account is locked out

<3 Buttons>"ok" "cancel" "apply"

Look at the checkbox labeled "password never expires" , it should be checked. What You Can Do Is Uncheck It.

Tthe 'user must change password at next logon' box is unchecked. If you put a check in this box of course,
when you shut down the system will prompt for a new password!

I belive that there is a way to FIX this hole by right clicking on any account ans usind the menu below.
[set password...]
[all tasks]
[delete]
[rename]
[properties]
[help]

I'm not to sure how you can use the abov menu to disable the editing of an account but if there are any ideas then i would love to know.
