Enable the (Hidden) Administrator Account in Windows Vista
Many people have asked me where on earth the Administrator account has gone in Windows Vista. Quite simply, it hasn’t gone anywhere, it still exists however, Microsoft made a very smart move as far as I’m concerned and disabled the Administrator account by default.
To be quite honest, the average home user and, dare I say, ‘power user’ shouldn’t need to enable this account for any reason what so ever. Those individuals who have already enabled the Administrator account and more importantly those who work exclusively with it are just asking for trouble and clearly have no idea about general system security.
If you have a genuine reason for enabling and working out of the administrator account, then please excuse my comment above as it doesn’t apply to you.
Enabling the Administrator Account
All warnings aside, if you still feel like being a cowboy, then here’s how you can enable and log in under the Administrator account.
First you’ll need to open a command prompt in administrator mode by right-clicking and choosing “Run as administrator” (or use the Ctrl+Shift+Enter shortcut from the search box in the Start menu).

Now type the following command:

You should see a message that the command completed successfully. Log out of Windows, and you’ll now see that you have a choice to log into the Administrator account.

There will be no password for this account. Once you are logged in as the Administrator, I strongly advise that you set one.
Disable the Administrator Account
Make sure you are logged in under your regular user account, and then open the command prompt in administrator mode (as above). Type the following command:

The administrator account will now be disabled, and shouldn’t show up on the login screen any more.
