Windows 11 includes a built-in administrator account that allows the computer manufacturers to install apps without creating a user account. For general users, however, the account is hidden by default to prevent unauthorized access.
Why is the Windows 11 administrator account disabled? The built-in administrator account on Windows 11 is disabled because it is not required and enabling it could impose a security risk. Many organizations disable the administrator accounts via group policy to secure their infrastructure.
Standard User accounts are for everyday computing. Administrator accounts provide the most control over a computer, and should only be used when necessary. Guest accounts are intended primarily for people who need temporary use of a computer.
Right-click the Start menu icon and choose Computer Management. On the left-side pane, select Local Users & Groups, then open the Users folder inside. Right-click the account you want to remove and choose Delete.
Sadly, there is no default password or admin default password for your Microsoft Windows. However, there are ways to regain access to your Windows if you don't remember your login info. If you have Windows 8, 10, or 11 and use a Microsoft account, the easiest way to do this is by running an online reset.
Using Local Users and Groups MMC (for server versions)
Open MMC and select "Local Users and Groups." Right-click the "Administrator" account and select "Properties." The "Administrator Properties" window appears.
The default local Administrator account is a user account for system administration. Every computer has an Administrator account (SID S-1-5-domain-500, display name Administrator). The Administrator account is the first account that is created during the Windows installation.
Replace "Administrator" with your built-in administrator account's name ("Administrator" by default), and replace the "pwd" with your new password. If you want to remove the built-in administrator password, type net user Administrator and hit Enter. That's it.
Difference between administrator and built in administrator
The built in administrator account has all of the control of the computer, UAC does not run when running built in administrator Account. But in standard Admin Account, User Account control Runs.
An administrator account is similar to a standard account but with some additional privileges. These privileges allow you to manage system files or do anything without requiring confirmation. With an administrator account, you can also access all those files that other users own on the same computer.
Built-in administrator account deals with the local machine while domain admin is with Domain. Most of the time local administrative account is required when there is network logon problem or some issue with domain admin account.
One of the easiest ways to reset your PC without a password is by issuing the Restart command while pressing the SHIFT key. This allows us to invoke the same Reset operation as from the Windows Repair menu. On the Choose an option screen, click Troubleshoot: Reset your PC or see advanced options. Choose Reset this PC.
