一些用户在Microsoft Defender^{(Microsoft Defender)}中看到“此设置由您的管理员管理^{(This setting is managed by your administrator)}”消息，因此，他们要么无法启用所有三个设置——实时保护^{(Real-time protection)}、云提供的保护^{(Cloud-delivered protection)}和自动样本提交^{(Automatic Sample submission)}，要么其中。

此设置由您的管理员管理 - Defender

您可能会看到此消息 此设置由您的管理员管理，用于^{(This setting is managed by your administrator)}Windows 安全^{(Windows Security)}中的以下功能：

1. 实时保护
2. 云交付保护
3. 自动样品提交。

通常，这意味着这些设置确实是由您的系统管理员配置的，与他讨论这个问题是有意义的。但是，如果您是管理员，那么您可以采取这些措施来解决问题。

1. 检查您是否使用任何 3rd 方工具
2. 扫描病毒和恶意软件
3. 删除 Windows Defender 注册表^{(Delete Windows Defender Registry)}项
4. 删除反间谍软件
5. 检查注册表^{(Check Registry)}或组策略^{(Group Policy)}设置。

让我们详细谈谈它们。

1]检查^(Check)您是否使用任何第三方工具

如果您使用3rd-party 调整工具来加强您的 Windows 10 安全性^{(harden your Windows 10 security)}，那么它可能通过注册表^(Registry)或组策略^{(Group Policy)}进行了这些更改。

您可能想要识别并卸载它或使用其重置为 Windows 默认^{(Reset to Windows defaults)}按钮，看看是否有帮助，

2]扫描病毒和恶意软件

要解决此问题，您首先需要做的是扫描您的计算机以查找病毒和恶意软件。要删除恶意软件，我们不建议使用任何第三方反恶意软件，因为它们可以将自己注册为主要保护；因此，我们将使用Microsoft Defender。

为此，请按照规定的步骤操作：

1. Win Win + I启动设置^(Settings)
2. 单击Update & Security > Windows Security > Open Windows Security。
3. 单击Virus & threat protection > Scan options > Microsoft Defender Offline scan > Scan now。

让它扫描您的计算机并删除病毒。

检查它是否解决了问题。如果这不能解决您的问题，您可以尝试下一个解决方案。

3]删除Windows Defender注册表

在注册表编辑器^{(Registry Editor)}中删除Windows Defender 密钥^{(Windows Defender Key)}对我有用，而且肯定对你有用。因此，为此，请从“开始”菜单启动^{(Start Menu)}注册表编辑器^{(Registry Editor)}并导航到以下位置。

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

右键单击Windows Defender，选择导出^(Export)，在您的 PC 上（最好在桌面^(Desktop)上）创建一个新文件夹^{(New Folder)}，打开它，将文件命名为“ Windows Defender ”，然后单击保存^(Save)。

现在，对所有子键执行此操作并删除Windows Defender。

最后，重新启动您的PC，问题将得到解决。

4]删除反间谍软件密钥

如果上述解决方案对您不起作用或您对注册表编辑器^{(Registry Editor)}不满意，您可以删除AntiSpyware来解决此问题。为此，通过Win + R >以管理员身份 启动命令提示符^{( Command Prompt)}>键入“ cmd” > Ctrl + Shift + Enter, 键入以下命令并按Enter。

REG DELETE "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /v DisableAntiSpyware

它会要求您确认您的操作，因此请按“ Y ”来执行此操作。

最后，重新启动计算机，看看问题是否仍然存在。希望^(Hopefully)您的问题将得到解决。

这些解决方案肯定对你有用，因为它们对我有用。

5]检查注册表^{(Check Registry)}或组策略^{(Group Policy)}设置

现在您可能需要一些专业知识才能做到这一点。您必须手动检查设置。

您可以在以下注册表中找到^(Registry)Defender设置：

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection

在组策略下：

Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus

您将必须检查是否已配置^(Configured)任何内容。您需要确保它们未配置。

Windows Defender: This setting is managed by your administrator

Some users see, “This setting is managed by your administrator” message in Microsoft Defender, and because of this, they are either unable to enable all three settings – Real-time protection, Cloud-delivered protection, and Automatic Sample submission, or one of them.

This setting is managed by your administrator – Defender

You may see this message This setting is managed by your administrator for the following functions in Windows Security:

1. Real-time protection
2. Cloud delivery protection
3. Automatic Sample Submission.

Typically, this means that these settings have indeed been configured by your system administrator, and it would make sense to discuss this with him. But if you are the admin, then these are things you can do to fix the issues.

1. Check if you are using any 3rd party tool
2. Scan for virus and malware
3. Delete Windows Defender Registry key
4. Delete AntiSpyware
5. Check Registry or Group Policy settings.

Let us talk about them in detail.

1] Check if you are using any 3rd party tool

If you are using a 3rd-party tweak tool to harden your Windows 10 security, then maybe it made these changes via the Registry or Group Policy.

You might want to identify it and uninstall it or use its Reset to Windows defaults button and see if that helps,

2] Scan for virus and malware

The first and foremost thing you need to do to fix the issue is to scan your computer for viruses and malware. To delete malware, we won’t recommend using any third-party anti-malware software as they can register themselves as the primary protection; therefore, we are going to use Microsoft Defender.

To do that, follow the prescribed steps:

1. Launch Settings by Win + I
2. Click Update & Security > Windows Security > Open Windows Security.
3. Click Virus & threat protection > Scan options > Microsoft Defender Offline scan > Scan now.

Let it scan your computer and delete the virus.

Check if it fixes the problem. If this didn’t fix your issue, you could try the next solution.

3] Delete Windows Defender Registry

Deleting Windows Defender Key in the Registry Editor has worked for me and will certainly work for you. So, to do that, launch Registry Editor from the Start Menu and navigate to the following location.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Right-click on Windows Defender, select Export, create a New Folder on your PC (preferably on the Desktop), open it, name the file “Windows Defender,” and click Save.

Now, do this for all the sub-keys and delete Windows Defender.

Finally, restart your PC, and the problem will be fixed.

4] Delete AntiSpyware key

If the above solution didn’t work for you or you are not comfortable with Registry Editor, you can delete AntiSpyware to fix this issue. To do that, launch Command Prompt as an administrator by Win + R > type “cmd” > Ctrl + Shift + Enter, type the following command and hit Enter.

REG DELETE "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /v DisableAntiSpyware

It will ask you to confirm your action, so hit “Y” to do that.

Finally, restart your computer and see if the issue persists. Hopefully, your problem will be fixed.

These solutions will definitely work for you as they worked for me.

5] Check Registry or Group Policy settings

Now you may need a bit of expertise to do this. You have to check the settings manually.

You can find the Defender settings in Registry under:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection

And in Group Policy under:

Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus

You will have to check if any have been Configured. You need to make sure they’re Not configured.
