Windows 10: SIGN INTO MY LAPTOP AS ADMINISTRATOR

I need help, please.I forget my password as an administrator on my laptop. I have been using it as a "guest" but now need to sign in as administrator.Can anyone help me, please?Can Microsoft please help me?Thank you.

:)

 

Administrator level User

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?

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.

 

Sign in with a Microsoft account instead. Administrator account

I have Windows 10 Pro since its release. Today, I decided to switch the email account for the computer administrator account. The following steps outline the sequence of events;

1. I logged in as a local account.
2. Clicked on Sign in with a Microsoft account instead
3. Followed the steps prompted. I entered my email of choice and the corrected password, then verified through the authenticator app.
4. I was asked to enter the password again, and now I am getting an error message that the password is incorrect
   but the password is correct 100%
5. Researched possible solutions
   • Used the English (United States) keyboard
   • Used on-screen keyboard
   • Reverting to Windows 7 is not possible as I never had it on my laptop
   • Reset my password
     • Nth worked

Please help me sign to my email account on this computer as an administrator
