您可以通过完成以下检查来验证是否安装了Windows PowerShell版本：

单击开始，单击所有程序，单击附件，单击Windows PowerShell，然后单击Windows PowerShell。在Windows PowerShell控制台中，在命令提示符处键入以下命令，然后按ENTER键：获取主机|选择对象版本

您将看到如下输出：

Version
-------
3.0

这是一个很老的问题，但仍然相关，只是问题的性质在2023年有所不同。找到版本很容易，但首先我们必须启动正确的可执行文件。为此，我们基本上回到了注册表中。

reg query "HKLM\SOFTWARE\Microsoft\PowerShell\1" /v Install >nul 2>&1
if %ERRORLEVEL% EQU 0 (
  :: Default to PowerShell 5 if both are installed
  set PSEXE=powershell
) else (
  set PSEXE=pwsh
)
echo Using %PSEXE%
%PSEXE% -ExecutionPolicy bypass -command "& { ... ; exit $LASTEXITCODE }"

通过检查环境变量可以获得其他提示，但我认为测试注册表中的“Windows”PowerShell是最安全的。

要确定是否安装了PowerShell，可以检查注册表中是否存在

HKEY_LOCAL_MACHINE\Software\Microsoft\PowerShell\1\Install

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3

如果存在，则值是否为1（对于已安装），如博客文章“检查是否已安装PowerShell和版本”中所述。

要确定安装的PowerShell版本，可以检查注册表项

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine\PowerShellVersion

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine\PowerShellVersion

要确定从.ps1脚本安装的PowerShell版本，可以使用以下一行程序，如PowerShell.com中“我正在运行的PowerShell版本”中所述。

$isV2 = test-path variable:\psversiontable

同一站点还提供了一个返回版本的函数：

function Get-PSVersion {
    if (test-path variable:psversiontable) {$psversiontable.psversion} else {[version]"1.0.0.0"}
}

这是“批处理文件获取powershell版本”的顶级搜索结果，因此我想提供一个基本示例，说明如何根据powershell版本在批处理文件中执行条件流

通用示例

powershell "exit $PSVersionTable.PSVersion.Major"
if %errorlevel% GEQ 5 (
    echo Do some fancy stuff that only powershell v5 or higher supports
) else (
    echo Functionality not support by current powershell version.
)

真实世界示例

powershell "exit $PSVersionTable.PSVersion.Major"
if %errorlevel% GEQ 5 (
    rem Unzip archive automatically
    powershell Expand-Archive Compressed.zip
) else (
    rem Make the user unzip, because lazy
    echo Please unzip Compressed.zip prior to continuing...
    pause
)
