A. XP introduces the option to have a password hint, which is useful in a workgroup (this option isn't available in a domain). To set a password hint, perform the following steps:
- Start the User Accounts Control Panel applet (Start, Control Panel, User Accounts).
- Select the account for which you want to add a password hint.
- Click Change the password.
- Enter your password in the two locations; in the bottom area, type your password hint.
- Click Change Password.
These hints are stored in the registry under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Hints\\[user name\]\(Default) key, and you can change them there as well.
