一些Windows PC 用户可能会面临在操作中心^{(Action Center)} 弹出的应用默认重置^{(An app default was reset)}循环通知。您会注意到各种应用程序的随机弹出窗口经常一个接一个地重复，桌面上的图标闪烁并且PC运行缓慢，这使您无法正常使用计算机。在今天的帖子中，我们将介绍原因，然后提供您可以尝试帮助解决此问题的可能解决方案。

此问题是由Windows 更新^{(Windows Update)}中的错误引起的，该错误会重置或尝试将默认应用重置回原来的状态（通常是UWP应用）。Windows 10 这样做的原因是，它认为第三方应用程序通过不正确的方法更改了文件关联。因此 Windows 会重置文件关联/默认应用程序。

在 Windows 11/10 上重置了应用默认值

An app default was reset. An app caused a problem with the default app setting, so it was reset.

如果您遇到此问题，您可以尝试以下我们推荐的任何解决方案，看看哪些解决了问题。

1. 将您的默认^(Default)程序设置回您想要的样子
2. 使用免费软件停止重置我的应用程序^{(Stop Resetting My Apps)}
3. 卸载并隐藏^(Hide)最近安装的Windows 更新^{(Windows Update)}
4. 删除 Windows 11/10 原生应用
5. 使用 Microsoft 帐户登录
6. 打开对焦辅助。

让我们看看解决方案中涉及的步骤的描述。

1]将^(Set)您的默认^(Default)程序设置回您想要的样子

在Windows 10中，要设置默认应用程序，您必须转到Settings > Apps > Default应用程序。您甚至可以按文件类型或协议选择默认应用程序，并按应用程序设置默认值。

这篇文章将向您展示如何更改默认程序设置。

2]使用^(Use)免费软件停止重置我的应用程序^{(Stop Resetting My Apps)}

您可以使用这个名为停止重置我的应用程序^{(Stop Resetting My Apps)}的免费软件。它是一个免费工具，可防止Windows 10^{(Windows 10)}自动重置默认应用程序、程序和文件关联。

3]卸载^(Uninstall)并隐藏^(Hide)最近安装的Windows Update

如果您在安装一些新程序、软件、应用程序或Windows 更新^{(Windows Updates)}后开始遇到“应用程序默认设置已重置”弹出通知循环，您可以考虑卸载程序^{(uninstalling the program(s))}和/或卸载 Windows 更新^{(uninstall the Windows Update)}以解决问题。然后您可能需要隐藏更新。

4]删除Windows 10本机应用程序

Windows 10通常会自动将默认应用程序重置为其内置应用程序，例如视频、音频和图像应用程序。但是，您可以从Windows 10^{(Windows 10)}中删除内置应用程序，以避免重复弹出“应用程序默认设置已重置”，前提是您已经安装了具有类似功能的第三方程序或软件。您可以将此类第三方应用程序设置为默认应用程序。

要使用 PowerShell 删除本机 UWP 应用^{(remove the native UWP apps using PowerShell)}，请执行以下操作：

按Windows键 + X，当跳转列表出现时，按 A 以launch PowerShell in admin/elevated mode。

将下面的命令复制并粘贴到窗口中，然后按Enter。（注意：^(Note:) 两个星号代表任意长度的任意序列，因此您无需输入应用程序的全名。）

get-appxpackage *photos* | remove-appxpackage

此示例适用于照片^(Photos)应用程序，如果您遇到其他内置应用程序的问题，请替换应用程序的名称。

当您想要恢复应用程序时，只需将下面的命令行复制并粘贴到Windows PowerShell ( Admin ) 环境中，然后按 Enter^(Enter)。

Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

5]使用微软帐户

如果您使用本地帐户登录，^{(signed in with a local account)}请先尝试切换到 Microsoft 帐户。一些用户报告更改为 Microsoft 帐户为他们解决了“应用默认设置已重置”通知错误。

要从本地帐户切换到Microsoft 帐户^{(Microsoft Account)}，请执行以下操作：

• 按 Windows 键 + I启动^{(I )}设置应用程序^{(launch the Settings app)}。
• 选择帐户。^(Accounts.)
• 单击左侧窗格中的您的信息^{(Your Info)}。
• 选择使用 Microsoft 帐户登录^{(Sign in with a Microsoft Account)}选项，然后按照屏幕上的任何其他说明进行操作。

6]打开对焦辅助

如果“应用程序默认设置已重置”弹出通知对您在Windows 10^{(Windows 10)}上的软件使用没有影响，那么您可以禁用弹出窗口以停止分心。

就是这样：

• 右键单击右下角^{(Right-click)}的通知图标。
• 选择焦点辅助^{(Focus Assist)}。并使用它。

它不会停止弹出窗口，但不会打扰您。

我希望这对你有用。^{(I hope this works for you.)}

An app default was reset notification error on Windows 11/10

Ѕome Windows PC users might be faced with the An app default was reset loop notifications popping up in the Action Center. You’ll notice the random popups for various apps repeat one after another often with the icons on the desktop flickering and PC running slowly, which prevents you from working with the computer normally. In today’s post, we will present the cause and then provide the possible solutions that you can try to help remediate this issue.

This issue is caused by a bug in the Windows Update that either resets or tries to reset the default app back to what it originally was (usually to the UWP apps). The reason why Windows 10 does this is because, it thinks that the third-party application changed the file associations by incorrect methods. So Windows resets the file associations/default apps.

Let’s see the description of the steps involved in the solutions.

3] Uninstall and Hide recently installed Windows Update

You may then need to Hide the Update.

4] Remove Windows 10 native app

Windows 10 often resets the default app to its built-in applications automatically, like video, audio and image apps. However, you can remove the built-in apps from Windows 10 to avoid the repeated popups of “An app default was reset” on condition that you’ve third-party programs or software with similar features in place. You can set such third-party applications as your default apps.

Copy and paste the command below into the window and hit the Enter. (Note: The two asterisks stand for any sequence of any length so that you don’t need to type the full name of the app.)

get-appxpackage *photos* | remove-appxpackage

This example is for the Photos app if you’re having the issue with another in-built app, substitute the name of the app instead.

When you want to restore the apps, just copy and paste the command line below into the Windows PowerShell (Admin) environment and hit Enter.

Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Here’s how:

• Right-click the notification icon on the bottom right.
• Select Focus Assist. and use it.
