您知道您可以修改用户帐户控制 (UAC)(User Account Control (UAC))设置来更改Windows 10中的安全级别(security level)吗？尽管大多数用户几乎不知道它的存在，但Windows 10用户帐户控制 (UAC)(User Account Control (UAC))是一项核心安全功能(core security feature)，可防止应用对您的计算机或设备(computer or device)进行未经授权的更改。阅读本指南以了解如何更改UAC通知级别并确定您多久收到一次“您要允许此应用程序对您的 PC 进行更改吗？” ("Do you want to allow this app to make changes to your PC?")Windows 10 中的提示：
首先(First)要做的事：关于Windows 10中的用户帐户控制(User Account Control)
自Windows Vista(Windows Vista)以来，用户帐户控制 (UAC)(User Account Control (UAC))一直是Windows 安全(Windows security)系统的一部分。最初被认为太烦人，后来得到了改进。结果是您在Windows 10中遇到的更轻松的UAC版本。当您运行需要管理员权限才能运行的桌面应用程序(desktop app)或更改需要管理员批准的重要系统设置时，会弹出Windows 10用户帐户控制。(User Account Control)
需要管理员权限并可能触发UAC提示的任务（例如以管理员身份运行(Run)）标有黄色和蓝色安全盾牌图标(security shield icon)。
在更改Windows 10中UAC的(UAC)安全级别(security level)之前，我们建议您通过阅读了解更多关于用户帐户控制(User Account Control)、它的作用以及为什么必须保持打开状态的信息：什么是UAC（用户帐户控制(User Account Control)）以及为什么永远不要关闭它。
如果您之后仍想更改其设置，请记住您需要管理权限才能修改用户帐户控制(User Account Control)安全级别。
如何访问Windows 10中的用户帐户控制设置(User Account Control Settings)
要更改UAC的工作方式，您需要访问“用户帐户控制设置”("User Account Control Settings")窗口。最简单的方法是在任务栏的搜索字段中输入(search field)“uac”。然后单击或点击(click or tap)“更改用户帐户控制设置”("Change User Account Control settings")或右侧的“打开”选项。(Open)
这将打开“用户帐户控制设置”("User Account Control Settings")窗口，您可以使用它来更改Windows 10中的安全级别(security level)。
您可以通过打开控制面板并访问(Control Panel and accessing)："System and Security -> Security and Maintenance -> Change User Account Control settings."
哪个UAC 通知(UAC notification)级别是默认的？
“用户帐户控制设置”("User Account Control Settings")窗口只有一个滑块，您可以使用它来调整“何时收到有关计算机更改的通知("when to be notified about changes to your computer)。”默认情况下，Windows 10用户帐户控制(User Account Control)设置为“仅在以下情况下通知我”应用程序尝试更改我的计算机”("Notify me only when apps try to make changes to my computer")安全级别。
仍然安全，虽然不是您可以使用的最严格的选项，但选择此默认安全级别(default security level)可确保UAC仅在程序进行需要管理权限的更改之前通知您。如果您手动对Windows(Windows)进行更改，则不会收到UAC提示。
因为仅当应用程序或文件(app or file)想要进行更改时才会弹出UAC ，因此与最高和最严格的(UAC)安全级别(security level)“始终通知”("Always notify")相比，此设置更不烦人且安全性更低- 这也会触发UAC干预以确认用户操作。
如何在Windows 10中更改(Windows 10)用户帐户控制级别(User Account Control level)
“用户帐户控制设置”("User Account Control Settings")窗口的滑块上有四个可用选项。要更改Windows 10中UAC提供的安全级别(security level)，只需通过单击或点击所需级别将滑块移动到适当的位置。您还可以单击或点击滑块并将其拖动到要使用的选项。
检查右侧的窗格，了解每个设置如何影响 Windows 10 安全通知的简要说明。我们在什么是UAC（用户帐户控制(User Account Control)）中详细讨论了四个安全级别之间的差异，以及为什么永远不要关闭它。做出选择，然后单击或点击确定(OK)。
您可能会收到用户帐户控制(User Account Control)提示，要求您确认此更改。
重要提示：(IMPORTANT:)您需要重新启动 Windows 10计算机或设备(computer or device)，然后才能应用新的用户帐户控制(User Account Control)设置。
禁用UAC 或哪个 UAC 级别(UAC or Which UAC level)提供最低级别的安全性？
如果您仔细阅读我们的指南坚持不关闭UAC并且您仍然决定禁用它，请将滑块移动到底部从不通知(Never notify)选项，即最低级别的安全性。这将关闭用户帐户控制(User Account Control)，使恶意程序更容易感染和控制您的 Windows 10计算机或设备(computer or device)。从好的方面来说，烦人的通知会停止，因为所有应用程序都可以在未经您许可的情况下按照自己的意愿进行操作。
提示：(TIP:)如果您因为相同的应用程序或游戏启动器不断触发它而禁用(apps or game launchers)UAC，请首先考虑使用Windows 任务计划(Windows Task Scheduler)程序在没有UAC提示和管理员权限的情况下运行应用程序。
您使用的是哪个UAC 级别，为什么？(UAC level)
虽然许多人觉得通知很烦人，但Windows 10 用户帐户控制(User Account Control)对于系统的安全性至关重要。我们始终在推荐的（默认）级别启用UAC，以防止任何不需要的恶意软件。你呢？您(Did)是否提高或降低了安全级别(security level)？在您关闭本教程之前，请随时在下面的评论中与我们分享您当前使用的UAC级别以及原因。(UAC)
How to change the User Account Control (UAC) level in Windows 10
Did yoυ knоw you сan modify the User Account Control (UAC) settings to change the security level in Windows 10? Although most users are barely aware of its existence, the Windows 10 User Account Control (UAC) is a core security feature that prevents apps from making unauthorized changes to your computer or device. Read this guide to learn how to change the UAC notification levels and decide how often you get the "Do you want to allow this app to make changes to your PC?" prompt in Windows 10:
First things first: About the User Account Control in Windows 10
The User Account Control (UAC) has been part of the Windows security system since Windows Vista. Initially considered too annoying, it has since been improved. The result is the more relaxed UAC version you come across in Windows 10. The Windows 10 User Account Control pops up when you run a desktop app that requires administrator permissions in order to function or are changing important system settings requiring administrative approval.
Tasks that require administrator privileges and are likely to trigger a UAC prompt, like Run as administrator, are marked by a yellow and blue security shield icon.
Before changing the security level of the UAC in Windows 10, we recommend learning more about the User Account Control, its role, and why it is essential to keep it turned on, by reading: What is UAC (User Account Control) and why you should never turn it off.
If you still want to change its settings afterward, keep in mind that you need administrative permissions to modify the User Account Control security level.
How to access the User Account Control Settings in Windows 10
To change the way UAC works, you need to access the "User Account Control Settings" window. The easiest way to do that is by typing "uac" into your taskbar's search field. Then click or tap on "Change User Account Control settings" or on the Open option on the right.
This opens the "User Account Control Settings" window, which you can use to change the security level in Windows 10.
You can get to the same place by opening the Control Panel and accessing: "System and Security -> Security and Maintenance -> Change User Account Control settings."
Which UAC notification level is the default?
The "User Account Control Settings" window only has one slider, and you can use it to adjust "when to be notified about changes to your computer." By default, the Windows 10 User Account Control is set to the "Notify me only when apps try to make changes to my computer" security level.
Still secure, while not the strictest option you can use, selecting this default security level ensures that the UAC notifies you only before programs make changes requiring administrative permissions. If you manually make changes to Windows, you don't get a UAC prompt.
Because the UAC pops up only if an app or file wants to make changes, this setting is less annoying and less secure than the top and strictest security level, "Always notify" - which also triggers UAC intervention to confirm user actions.
How to change the User Account Control level in Windows 10
There are four options available on the slider in the "User Account Control Settings" window. To change the security level provided by the UAC in Windows 10, simply move the slider to the appropriate position by clicking or tapping on the desired level. You can also click or tap on the slider and drag it to the option you want to use.
Check the pane on the right for a brief description of how each setting impacts your Windows 10 security notifications. We went over the differences between the four security levels at length in What is UAC (User Account Control) and why you should never turn it off. Make your choice, and then click or tap OK.
You might receive a User Account Control prompt asking you to confirm this change.
IMPORTANT: You need to restart your Windows 10 computer or device before the new User Account Control settings are applied.
Disable UAC or Which UAC level provides the lowest level of security?
If you went over our guide insisting not to turn off UAC and you're still determined to disable it, move the slider to the bottom Never notify option, the lowest level of security. This turns the User Account Control off, making it easier for malicious programs to infect and take control of your Windows 10 computer or device. On the bright side, the annoying notifications stop, as all apps are allowed to do as they wish without your permission.
TIP: If you are disabling UAC because the same apps or game launchers keep triggering it, please consider using the Windows Task Scheduler to run apps without UAC prompts and admin rights first.
Which UAC level are you using and why?
While many find the notifications an annoyance, the Windows 10 User Account Control is essential for the security of your system. We always keep UAC enabled at the recommended (default) level to prevent any unwanted malware. What about you? Did you increase or decrease your security level? Before you close this tutorial, do not hesitate to share with us which UAC level you're currently using and why in the comments below.
