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'

使用简单的PowerShell命令在注册表中设置此参数;

New-PSDrive -Name HKCR -PSProvider Registry -Root HKEY_CLASSES_ROOT
Set-ItemProperty -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\open\command" -name '(Default)' -Value '"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -noLogo -ExecutionPolicy unrestricted -file "%1"'

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

在我的子文件夹中放一个简单的.cmd文件和同名的.ps1文件，例如，一个名为“foobar”的脚本会有“foobar. exe”。Ps1”和“foobar.cmd”。所以要运行.ps1，我所要做的就是从资源管理器中单击.cmd文件或从命令提示符中运行.cmd。我使用相同的基本名称，因为.cmd文件将自动使用自己的名称查找.ps1。

::====================================================================
:: Powershell script launcher
::=====================================================================
:MAIN
    @echo off
    for /f "tokens=*" %%p in ("%~p0") do set SCRIPT_PATH=%%p
    pushd "%SCRIPT_PATH%"

    powershell.exe -sta -c "& {.\%~n0.ps1 %*}"

    popd
    set SCRIPT_PATH=
    pause

pushd/popd允许您从命令提示符启动.cmd文件，而不必更改到脚本所在的特定目录。它将改变到脚本目录，然后当完成返回到原来的目录。

如果您希望命令窗口在脚本结束时消失，也可以取消暂停。

如果我的.ps1脚本有参数，我会使用. net Forms使用GUI提示来提示它们，但也要使脚本足够灵活，以便在我想要传递参数时接受参数。这样我就可以从资源管理器中双击它，而不必知道参数的详细信息，因为它会用列表框或其他形式询问我需要什么。

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):
