自動登錄使您可以輕松地配置Windows的內置自動登錄機制。而不是等待用戶輸入他們的姓名和密碼,Windows使用的憑據,您輸入自動登錄,在注冊表中加密,自動登錄到指定的用戶。

Autologon enables you to easily configure Windows’ built-in autologon mechanism. Instead of waiting for a user to enter their name and password, Windows uses the credentials you enter with Autologon, which are encrypted in the Registry, to log on the specified user automatically.
