这是我默认以admin身份运行的脚本:

Powershell.exe -Command "& {Start-Process PowerShell.exe -Verb RunAs -ArgumentList '-File """%1"""'}"

你需要将它作为默认值粘贴到regedit中:

HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\Open\Command

或者这里有一个脚本，将为您做:

$hive = [Microsoft.Win32.RegistryKey]::OpenBaseKey('ClassesRoot', 'Default')
$key = $hive.CreateSubKey('Microsoft.PowerShellScript.1\Shell\Open\Command')
$key.SetValue($null, 'Powershell.exe -Command "& {Start-Process PowerShell.exe -Verb RunAs -ArgumentList ''-File """%1"""''}"')

我在几年前写了这个(以管理员权限运行):

<#

您需要调整注册表。 首先，为HKEY_CLASSES_ROOT配置一个PSDrive，因为默认情况下没有设置。它的命令是:

New-PSDrive HKCR Registry HKEY_CLASSES_ROOT

现在您可以在HKEY_CLASSES_ROOT中浏览和编辑注册表项和值，就像在常规HKCU和HKLM PSDrives中一样。

配置双击直接启动PowerShell脚本:

Set-ItemProperty HKCR:\Microsoft.PowerShellScript.1\Shell '(Default)' 0

在PowerShell ISE中配置双击打开PowerShell脚本:

Set-ItemProperty HKCR:\Microsoft.PowerShellScript.1\Shell '(Default)' 'Edit'

要恢复默认值(设置双击打开记事本中的PowerShell脚本):

Set-ItemProperty HKCR:\Microsoft.PowerShellScript.1\Shell '(Default)' 'Open'

我的解决方案是2022年 安装“PowerShell-7.2.2-win-x64.msi” 右键单击文件。Ps1，用“pwsh”更改为exec

Powershell注册表黑客和策略绕过从未对我起作用。

从http://www.howtogeek.com/204166/how-to-configure-windows-to-work-with-powershell-scripts-more-easily:

为HKEY_CLASSES_ROOT\Microsoft.PowerShellScript设置默认值。1\Shell到0

您可以将ps1文件的默认文件关联设置为powershell.exe，这将允许您通过双击它来执行powershell脚本。

在Windows 10中，

右键单击ps1文件 单击“打开” 点击选择另一个应用程序 在弹出窗口中，选择“更多应用程序” 滚动到底部，选择“在这台PC上寻找另一个应用程序”。 浏览并选择C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe。 列表项

这将改变文件关联，ps1文件将通过双击它们来执行。通过将notepad.exe设置为默认应用程序，您可以将其更改为默认行为。
