ok, then you did not use your microsoft account on the computer but a local account
In this event, the only way to remove the password ***** ***** reinstall of windows.
This will result in the loss of your data from the computer but this is unavoidable, it is the whole reason for the security
In order to do this, hold the left SHIFT key and with it held down, click on the power icon and click on restart.
Keep shift held down until it has restarted and you are at a menu.
Choose from the menu troubleshoot, then reset my pc
You must then choose the option to remove all files
Once done it will then reinstall windows so it will be as new, like when you first received it.
Then I strongly advise you set it up using a microsoft account, using the gmail account you gave and the password ***** gave you.
Once done, you will be able to use the computer again.
