Windows 10: Windows Administrator Sign in

I am currently running Windows 10 on my laptop. Recently I updated my laptop's BIOS but it changed my security settings. I used to log in using a Pin but now its showing that your system's security settings has been changed plz login with the password. I created the password a long time ago & do not remember it now. It doesn't show any option of Forgot Password or a security question. I also did not created a Password reset disk. What to do now?

I've also tried third party softwares to break the lock but nothing happened.

Plz help me out.

Use Option Five again, but this time boot from a Windows 10 install usb or recovery drive. You only get asked to select an administrator account if you boot from the system's own Advanced Startup.

 

administrator can't sign in

I appreciate your response. There is a possibility that your user account is not an administrator and that is the reason why the device is having an issue with receiving a remote control assistance. Since you are also having an issue with accessing the administrator
account of your wife, I suggest enabling the built-in administrator on your Windows 10. Using the built-in administrator account, you'll be able to make your user account as an administrator.

To enable the built-in administrator account, follow these steps:

• On Search type CMD to open the Command Prompt. Right click on CMD then choose Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Yes.
  
• In the Command Prompt window, type net user administrator /active:yes then hit the Enter key.
  
• You should see a message that the command completed successfully. Log out, and you’ll now see the Administrator account as a choice on the login screen.

Once you sign into the PC using the built-in administrator, follow these steps to make your user profiles as an administrator:

• Open the Settings app.
• Choose Accounts and then click on Other people.
• Click on your user account and then click on Change account type button.
• Change the account type to Administrator and then click OK.
• Log into your user profile.

Note: The built-in administrator account has more privileges than a regular administrator account. Privileges that can easily generate a conflict on your system. We only recommend enabling the built-in administrator account for troubleshooting purposes and
you have to disable it once you are done.

To disable the built-in administrator account, access the Command Prompt with administrator privileges. Type the command net user administrator /active:no then hit the Enter key. The built-in administrator account will now be disabled, and
shouldn’t show up on the login screen.

Let me know if further assistance is needed.

Got the laptop. It's a Lenovo G500 so possibly has Lenovo stuff in the way? Anyway, booted it normally and it opens into a regular account without admin privileges. Rebooted it into Recovery mode (per Option 5) and get Lenovo logo and Preparing Automatic Repair message; then Select Account + "You need to sign in as an administrator to continue but there aren't any administrator accounts on this PC". There is an option "Forgot your password or don't see your account?" but selecting that brings up a screen which should list admin accounts but there aren't any. Pressing the only option on that page Restart leads eventually to a BSOD with Stop code: 0xc00002e3 (which I know is misconfigured o/s or missing or damaged system files).

Can anybody suggest next steps in resolving this?
