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

创建一个快捷方式，像这样的“目标”:

powershell.exe -command "& 'C:\A path with spaces\MyScript.ps1' -MyArguments blah"

我在几年前写了这个(以管理员权限运行):

<#
.SYNOPSIS

    start its execution with PowerShell.
.DESCRIPTION
    This operation bring (partly) .PS1 files to the level of .VBS as far as execution
    through Explorer.exe is concern.
    This operation is not advised by Microsoft.

我使用了这个(只需要运行一次);还要确保你有执行的权利:

从PowerShell提升权限:

Set-ExecutionPolicy=RemoteSigned

然后从一个bat文件:

-----------------------------------------

 ftype Microsoft.PowerShellScript.1="C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe" -noexit ^&'%%1'

 assoc .ps1=Microsoft.PowerShellScript.1

-----------------------------------------
auto exit: remove -noexit 

瞧;双击*。Ps1会执行它。

请注意，PowerShell的安全特性之一是用户不能通过双击启动脚本。如果要修改此设置，请务必小心。另一种选择可能是打包脚本。像PrimalScript这样的编辑器可以做到这一点。用户仍然需要安装PowerShell，然后他们可以双击exe。听起来你的团队需要一点教育。

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
