Automatically finish setting up PC after update
Some updates require you to restart your PC and sign in to Windows in order to finish installing the update, which means you might sign in to Windows and find you can’t use your PC until the update is finished. Windows 10 helps prevent this from happening by allowing Windows to use your sign in info to create a special token.
This token is used to automatically sign in after a restart, finish setting up your PC, and then lock your PC to help keep your account and personal info safe.
To use this option, select the Start button, select Settings > Update & security > Windows Update > Advanced options, and then select the check box next to Use my sign in info to automatically finish setting up my device after an update.
Note: It’s recommended you turn on BitLocker when using this option. This option isn’t available if your PC is joined to a domain or if work or email policies are applied to your PC.
