使用者帳號 每位使用這臺的人都應該要有不同的使用者帳號,這樣才能將您與別人的檔案隔離開來、每個人都能用自己習慣的設定使用電腦,並且這樣做也更加安全。除非你知道別人的密碼,否則無法取用其他使用者的帳號。 管理使用者帳號 新增使用者帳號 — Add new users so that other people can log in to the computer. Change your login screen photo — Add your photo to the login and user screens. 刪除使用者帳號 — 移除不會再使用電腦的使用者。 自動登入 — Set up automatic login for when you switch on your computer.
