Hi Teng Kiat,
So you went into the recovery environment(winRE), uninstalled the latest Windows update, and then saw the option to log in with a Microsoft account again on the login page?
Then obviously you are in luck, because usually this option is checked in the default login Settings of the system, then you will not see the option to log in with a Microsoft account on the login page:
And if you can't see this option, then the solution in my first reply is what you need to do next.
Anyway, I'm glad to hear that your problem has been resolved, but I still want to give you a warm tip to create a new local administrator account for your Surface, so as to avoid the embarrassment of having no account to log in to the system.
If you have any questions about using Microsoft products in the future, please feel free to post a new thread here.
