If you cant reset the Outlook password, or the microsoft account password ( which is basically the same thing )
Then the only way to get the computer working again is to factory reset it.
Heres how to do so, when you turn on the computer and get to the windows 10 login screen.
at the lower right click the power icon, hold down the shift key on your keyboard.. And then click restart.
You can release the shift key after you click restart.
When the computer restarts, it will be in the advanced boot options. You need to choose Reset the computer..
That will wipe out your windows account and let you reinstall windows.
Once complete, you will have a working computer again.
