Windows User Manager is the free desktop tool to easily and quickly manage all the User accounts on your Windows system.
On starting, it lists all user accounts along with following details for each user,
Account Type (Administrator/Normal User/Guest)
Account Status (Active/Disabled)
Password Status (Pwd Set/Not Set/Expired)
Last Logon Time
You can select a user from the list then Enable/Disable or Delete that account with just a click of button. This will be useful in recent systems (Win7, Win8 etc) where built-in Administrator account is disabled by default and using this tool you can quickly enable it.
