用户帐户控制(User Account Control)，简称UAC，是为了确保Windows计算机的安全而开发的。UAC不允许对操作系统进行任何未经授权的访问(System)。UAC确保系统中的更改仅由管理员进行，其他人不得进行。如果管理员不批准上述更改，Windows将不允许它发生。因此，它可以防止应用程序、病毒或恶意软件攻击进行任何类型的更改。今天，我们将讨论如何在 Windows 7、8 和 10 中启用用户帐户(Windows 7)控制(User Account Control)以及如何在Windows 7中禁用(Windows 7)UAC和更高版本。
如何在 Windows 10 PC 中启用 UAC
(How to Enable UAC in Windows 10 PC
)
如果您是管理员，每当您的系统中安装了新程序时，系统都会询问您：您要允许此应用程序对您的设备进行更改吗？(Do you want to allow this app to make changes to your device? )另一方面，如果您不是管理员，提示将要求您输入用户名和密码以访问所述程序。
(User Account Control)启动Windows Vista时，(Windows Vista)用户帐户控制是一个被误解的功能。许多用户试图卸载它，却没有意识到他们将自己的系统暴露在威胁之下。在此处阅读有关用户帐户控制如何工作的(How User Account Control Works here)Microsoft页面。
