Disabling security questions in Windows 10 pro

Instead of setting the password during the OOBE wizard, set it later. This hasn’t changed from earlier versions of Windows where you had to enter a password hint.

After the setup process is complete, press Ctrl+Alt+Del and select “Change a password”. You will be prompted to enter your old password (empty) and your new password.

If you already entered security questions, you’ll probably have to remove your password first and then use the Ctrl+Alt+Del method. Depending on the how you remove the password, you may lose access to EFS-encrypted files.

Like the password hint on earlier Windows versions, this probably cannot be deactivated on non-domain accounts.

Starting with Windows 10 build 18237, a new group policy was added for preventing the use of security questions for local accounts. Open Local Group Policy Editor and go to:

Computer Configuration\Administrative Templates\Windows Components\Credential User Interface

Prevent the use of security questions for local accounts

Look for a policy called "Prevent the use of security questions for local accounts" and enable it. Source

If you want to delete the security questions that was already set up for local account, open Registry Editor and go to: HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets. Delete any subkey that begins with L$_SQSA_. Source

Remove security questions for Windows 10 local account

You can create users without security questions by going into the "Local Users and Groups" panel within Computer Management. In there you have the option to create users with or without a password along with the settings like "change password on next login", or "set password to never expire". There is no place in there to setup a hint or security questions.

Note that by default account created there are only members of the users group and if you want them to be local admins, then you need to add "administrators" to their group.
