有时，在启动应用程序或网站时，Edge浏览器可能会显示提示，显示“此站点正在尝试打开此应用程序^{(This Site is trying to open this application)}”。如果这种行为只发生一次或两次，那么它是可以接受的，但超过它，它可能会令人烦恼。因此，如果您在Microsoft Edge 浏览器^{(Microsoft Edge browser)}或Google Chrome中经常看到此提示，那么这篇文章将展示您如何禁用它：

This Site is trying to open <application>

<Website> wants to open this application.

禁用此站点^(Site)正在尝试在Edge中打开此应用程序提示^(Edge)

上述错误行为似乎与“切换应用程序^{(switching apps)}”时观察到的行为相同，并且每次调用外部协议时都会出现。因此，系统会提示用户进行确认。执行以下操作以在Microsoft Edge中禁用它：

1. 打开注册表编辑器。
2. 导航^(Navigate)到策略 MicrosoftEdge 键
3. 双击ExternalProtocolDialogShowAlwaysOpenCheckbox。
4. 将默认值从 0 更改为 1
5. 关闭注册表编辑器^{(Registry Editor)}并重新启动您的 PC。

打开Windows 注册表编辑器^{(Windows Registry Editor)}。为此，请组合按Win+R，然后在出现的“运行^(Run)”对话框中，键入“ regedit ”并按“ Enter ”。

在打开的窗口中，导航到以下键 -

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge

切换到右窗格并双击名称为ExternalProtocolDialogShowAlwaysOpenCheckbox的键。

如果您看不到该条目，则需要创建一个新条目。

接下来，在出现的Edit String框中，将默认的Hexadecimal值从 0 更改为1。

完成后，关闭注册表编辑器^{(Registry Editor)}并退出^(Exit)。

最后，重新启动您的 PC。

由于您已启用此策略，因此您应该可以看到外部协议确认提示“始终允许”。^{(Always allow)}选中针对此选项标记的框以跳过站点上所有未来的协议确认提示。

当您禁用此策略时，将不会显示“始终允许^{(Always allow)}”复选框，并且每次调用外部协议时都会提示用户确认。

禁用此站点^(Site)正在尝试在Chrome中打开此应用程序提示^(Chrome)

要在Google Chrome^{(Google Chrome)}浏览器中禁用此提示，请导航至以下键：

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome

按如下方式更改此值：

• DWORD（32 位）：ExternalProtocolDialogShowAlwaysOpenCheckbox
• 数值数据：1（十六进制）

希望这可以帮助。

Disable This Site is trying to open this application - Edge or Chrome

At times, upon launching an app or a websitе, the Edge browser mаy display a prompt, reading ‘This Site is trying to open this application’. This behavior is acceptable if it occurs just once or twice but beyond it, it can be bothering. So if you see this prompt frequently in Microsoft Edge browser or in Google Chrome, then this post shows how you can disable it:

This Site is trying to open <application>

<Website> wants to open this application.

Disable This Site is trying to open this application prompt in Edge

The above-mentioned erroneous behavior seems to be of the same kind one observes when ‘switching apps’ and appears every time an external protocol is invoked. So, the user is prompted for confirmation. Do the following to disable it in Microsoft Edge:

1. Open the Registry Editor.
2. Navigate to \Policies\Microsoft\Edge key
3. Double-click on ExternalProtocolDialogShowAlwaysOpenCheckbox.
4. Change the default value from 0 to 1
5. Close the Registry Editor and restart your PC.

Open the Windows Registry Editor. For this, press Win+R in combination and in the ‘Run’ dialog box that appears, type ‘regedit’ and press ‘Enter’.

In the window that opens, navigate to the following key –

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge

Switch to the right-pane and double-click the key with the name – ExternalProtocolDialogShowAlwaysOpenCheckbox.

If the entry is not visible to you, you need to create a new one.

Next, in the Edit String box that appears, change the default Hexadecimal value from 0 to 1.

When done, close the Registry Editor and Exit.

Finally, restart your PC.

Since, you have enabled this policy, an external protocol confirmation prompt ‘Always allow’ should be visible to you. Check the box marked against this option to skip all future confirmation prompts for the protocol on the site.

When you disable this policy, the ‘Always allow’ checkbox won’t be displayed and the user will be prompted for confirmation every time an external protocol is invoked.

Disable This Site is trying to open this application prompt in Chrome

To disable this prompt in Google Chrome browser, navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome

Change this value as follows:

• DWORD (32-bit): ExternalProtocolDialogShowAlwaysOpenCheckbox
• Value Data: 1 (Hex)

Hope this helps.
