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。

源

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。

与UNIX shar (shell存档)具有相同精神的解决方案。

你可以把你的powershell脚本放在一个扩展名为.cmd的文件中(而不是.ps1)，并把它放在开头:

@echo off
Rem Make powershell read this file, skip a number of lines, and execute it.
Rem This works around .ps1 bad file association as non executables.
PowerShell -Command "Get-Content '%~dpnx0' | Select-Object -Skip 5 | Out-String | Invoke-Expression"
goto :eof
# Start of PowerShell script here

我在Windows 10和powershell 5.1上使用了这个方法:

右键单击.ps1文件 打开…… 选择另一个应用程序 将powershell.exe的位置复制到地址栏(默认情况下不会显示windows文件夹)，即C:\Windows\System32\WindowsPowerShell\v1.0 选择powershell.exe 选择“总是使用此应用程序打开。ps1文件” 单击OK

我在几年前写了这个(以管理员权限运行):
