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.
"Upon installation" (which I took to mean during the obligatory setup process you are forced to use when you first power up a new PC) I've found those questions to be unavoidable ONLY IF you skip setting a password for the user you are being forced to create.
It's my practice to setup a local administrator on each new machine even if it is joining a domain so I don't mind entering the user name and description etc., but the only way I can find to avoid those security questions is to leave the password field blank. Later on, once the obligatory setup process has finished, don't forget to add a password to that account because it is by default a local administrator account. When I do this using netplwiz I'm not asked to create any security questions.
