Question

所以我正在使用以下Powershell脚本：Set-RunOnce https://www.powershellgallery.com/packages/WindowsImageConverter/1.0/Content/Set-RunOnce.ps1

当我将驱动器号硬编码到（E：\ ServerInstall.ps1）中时，它就像一个超级按钮。但是我想确保此脚本可以从USB插入的任何驱动器盘符中运行。

如何在注册表中获取此更改的驱动器号？

我首先使用 -ExecutionPolicy Bypass 进行了尝试，但这也没有太大改变。

我也尝试过：

$ getusb = Get-WmiObject Win32_Volume -Filter“ DriveType ='2'”。   。\ Set-RunOnce.ps1 Set-RunOnce -Command

'％systemroot％\ System32 \ WindowsPowerShell \ v1.0 \ powershell.exe`   -ExecutionPolicy不受限制-文件$ getusb.Name \ ServerInstall.ps1'

->   $ getusb.Name \ ServerInstall.ps1最终在注册表中被硬编码，但是它不知道是什么   $ getusb.name是，所以脚本没有启动。

. .\Set-RunOnce.ps1
Set-RunOnce -Command '%systemroot%\System32\WindowsPowerShell\v1.0\powershell.exe `
-ExecutionPolicy Unrestricted -File (wmic logicaldisk where drivetype=2)
ServerInstall.ps1'

Set-RunOnce函数非常易于理解和调整。
我建议创建自己的派生函数来执行所需的操作，并改用它：

function Set-RunOnceForUSB {
    # get the driveletter from WMI for the first (possibly only) USB disk
    $firstUSB   = @(Get-WmiObject -Class Win32_LogicalDisk | Where-Object {$_.DriveType -eq 2} | Select-Object -ExpandProperty DeviceID)[0]
    # or use:
    # $firstUSB = @(Get-WmiObject Win32_Volume -Filter "DriveType='2'" | Select-Object -ExpandProperty DriveLetter)[0]

    # combine that with the name of your script file to create a complete path
    $scriptPath = Join-Path -Path $firstUSB -ChildPath 'ServerInstall.ps1'

    # create the command string. use double-quotes so the variable $scriptPath gets expanded
    $command = "%systemroot%\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Unrestricted -File $scriptPath"

    # next, add this to the registry same as the original Set-RunOnce function does
    if (-not ((Get-Item -Path HKLM:\Software\Microsoft\Windows\CurrentVersion\RunOnce).Run )) {
        New-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\RunOnce' -Name 'Run' -Value $command -PropertyType ExpandString
    }
    else {
        Set-ItemProperty -Path 'HKLM:\Software\Microsoft\Windows\CurrentVersion\RunOnce' -Name 'Run' -Value $command -PropertyType ExpandString
    }
}

Set-RunOnce从更改USB驱动器号运行ps1文件
