Windows 7,
I had three accounts now only one shows up, the admin and guest accounts have disappeared from welcome nor can i access them directly.
Try all programs...accessories, and right click ..."run as administrator" on the command prompt "cmd". you should get a black command prompt box. type
net user administrator /active:yes
*note the space before the forward slash.
if it says command completed successful, reboot and the admin account should show up in the login menu. If the command does not complete make sure you are "running as admin"
The built-in Administrator account which you have just started to use should not be used for your daily work. It should remain hidden. Using that account, create another admin account first. Then give the command net user administrator /active:no
to make it hidden again.
