Sent my old i5 Acer PC for repair just that th Windows 8.1 was crash after several attend to recover it but failed. Found that my PC can upgrade to Windows 10 with SDD drive. Good news that is not so expensive which only cost me B$144.00 with service charge.
After that I found there is no login password after the new Windows. So I create a account and manage to login with password.
But today I just want to login without any password, and go to setting - control panel - my account and found it was not easy to disable the login password. Finally after several searching, I found the way, it was at the following web site:
