How to Disable or Enable a User Account in Vista

Information
This will show you how to hide (disable) or unhide a user account from being accessed or seen in Vista. For example, from the Logon screens, Parental Controls, UAC, User Accounts, etc...

Note
An administrator account will still be able to navigate to and access the contents of the C:\Users\(user-name) folder of a disabled user account using Windows Explorer.
