Today I am going to show you how to enable an administrator account on Windows Vista. If you are receiving a message on Windows Vista stating that you do not have enough priviliges, then this fix is for you. The Windows Vista administrator account is disabled by default.
You can try enabling an administrator account on Windows Vista pretty quickly. Enable an administrator account on Windows Vista:
1. Open a command prompt with Administrative privileges by opening a "Start" Menu, and typing cmd in a search box, then press "Ctrl+Shift+Enter" or click a "Start" orb, go to "All Programs", then "Accessories", and right click "Command Prompt" and select Run as administrator.
2. Type a following in that command prompt and press Enter:
net user administrator /active:yes
3. Restart your computer and logon as Administrator.
You might want to set a password for that administrator account for at least a little protection. You can disable an administrative account, for added security when your finished performing those tasks that required administrative privileges. To disable an administrative account run a net user command demonstrated above while logged on an account with administrative privileges but not as the administrator account and replace yes with no.
net user administrator /active:no
