"I can't sign into Windows 10 and the screen flashes a message: Your account has been disabled. Please see your system administrator. There is no other account displaying on the screen. What can I do?"

This issue can result from various circumstances. Now, this post will show you two solutions to fix the problem.

• Solution 1: Activate built-in Administrator by hacking registry
• Solution 2: Create a new admin account with third-party tool

Solution 1: Activate built-in administrator by hacking registry

Step 1: On Windows 10 sign-in screen, click the Power button, then click the Restart button while pressing and holding the Shift key on your keyboard. This will start Windows 10 to "Choose an option" screen.

Step 2: Click Troubleshoot > Advanced options > Command Prompt. Then Windows 10 will restart and prepare Command Prompt.

Step 3: After the Command Prompt screen appears, the Administrator built-in Windows 10 is displayed on the screen, even it is in a disabled state. Click on it to continue.

Step 4: Then you are asked to type the password to continue. The password of a built-in administrator account is blank by default, so just leave the password field blank, and click Continue. If you have changed the password, enter it and click Continue. But if you've forgotten the password, you won't be able to continue and have to choose Solution 2 to fix the issue: Your account has been disabled. Please see your system administrator.

Step 5: After the command prompt window opens, type regedit and press Enter key to open Registry Editor.

Step 6: In the Registry Editor, click on HKEY_LOCAL_MACHINE, then click the File tab and select Load Hive.

Step 7: In the Load Hive dialog, select This PC, then open the disk drive where your Windows 10 system is installed, and navigate to Windows\System32\Config. Under the Config folder, double-click the SAM file to create a new key.

Step 8: Type a name for the new key and click OK. In my example, I name it as test.

Step 9: Now, navigate to HKEY_LOCAL_MACHINE\test\SAM\Domains\Account\Users. Under the Users folder, click the key named "000001F4", and then double-click the entry named "F" on the right pane.

Step 10: Locate the line that starts with "0038", then double-click the value data "11", type "10" to replace "11", and click OK. This will enable the built-in administrator in Windows 10.

Step 11: Close the Registry Editor and the command prompt dialog so that you can be back on the "Choose an option" screen. Click on Continue. Then Windows 10 will restart and automatically sign into the built-in administrator account.

Step 12: After you access the built-in administrator account, you can enable any other account that has been disabled.

Solution 2: Create a new administrator account with a third-party tool

Now that your account has been disabled and your Windows 10 system is locked out, you can use a third-party tool to create a new account that has administrative rights so that you can sign in Windows 10 with the new admin account and then enable the account that has been disabled. Steps are as follows.

Step 1: Create a bootable USB drive

On another working computer, download and install Windows Password Refixer tool. After the installation is complete, launch it and then follow its screen to burn it to a USB flash drive to create a bootable USB drive.

Step 2: Boot Windows 10 computer from USB drive

Connect the bootable USB drive to the Windows 10 computer, and set computer to boot from the USB drive. During the process of booting, you will see Windows PE load, and then "Windows Password Refixer" screen appears.

Step 3: Create a new administrator account

On Windows Password Refixer screen, click the Add User button, type a user name, and click OK. This will create a new account that has administrative rights on Windows 10.

Step 4: Sign in Windows 10 with the new admin account

After a new admin account is created, click the Reboot button and disconnect the bootable USB drive when prompted. Then the computer will restart and the new admin account will display on Windows 10 sign-in screen. Sign in Windows 10 with the new admin account.

Step 5: Enable the account that has been disabled

Open Computer Management app. Go to System Tools > Local Users and Groups > Users. Select the Users folder, double-click the account that has been disabled, then uncheck the checkbox next to "Account is disabled" and click OK, so that the account can be enabled.

The above are two solutions to solve the problem, "Your account has been disabled. Please see your system administrator."
