By default, an Administrator account has been created during the installation on Windows Vista and the latest series (Windows 7, 8 and 10) but not active. Generally Windows will create a new user with the type Administrator in the initial installation where the user can fill in a free name for it.
What if we want to activate it? If we try by clicking Start – Control Panel – Add or delete user accounts – Create a new account – fill with the Administrator then click Create Account then appears as shown below.
The message is informed that the name of the Administrator account already exists, as I informed in the first paragraph. For this reason, you only need to activate it in the following way :
1. Click Start – type cmd in the Search Box and after it appears, right-click on the program and select Run as administrator.
2. If Windows asks for a password, please enter the password, but if you don’t know it, then in this case, it means that only the Admin / IT party can process it.
3. If Windows does not require a password and the following image appears, type “net user administrator /active:yes” (without the quotes) then press Enter.
4. Return to Manage Accounts and have seen an Administrator account as shown below.
