如何实现右键注册表分支生成PowerShell注册表导入脚本？

方法1：添加右键菜单选项（永久生效） #

运行以下PowerShell脚本，直接给注册表编辑器添加「生成PowerShell导入脚本」的右键选项：

# 创建右键菜单项注册表路径
$menuPath = "HKCR:\Registry\shell\Export-PSScript"
New-Item -Path $menuPath -Force | Out-Null
Set-ItemProperty -Path $menuPath -Name "(Default)" -Value "生成PowerShell导入脚本"
Set-ItemProperty -Path $menuPath -Name "Icon" -Value "powershell.exe,0"

# 设置右键菜单触发命令
$commandPath = "$menuPath\command"
New-Item -Path $commandPath -Force | Out-Null
Set-ItemProperty -Path $commandPath -Name "(Default)" -Value @"
powershell.exe -NoExit -Command "`$keyPath = '%1'; `$outputPath = Join-Path (Get-Location) (`$keyPath.Split('\')[-1] + '_RegImport.ps1'); & {
    param(`$KeyPath, `$OutputPath)
    function Export-RegToPS {
        param(`$Key, `$Indent)
        `$indentStr = '  ' * `$Indent
        `$output = @()
        `$output += "`$indentStr`if (-not (Test-Path `$Key)) { New-Item -Path `$Key -Force | Out-Null }"
        # 导出当前键的所有值项
        foreach (`$value in Get-ItemProperty -Path `$Key -ErrorAction SilentlyContinue) {
            foreach (`$prop in `$value.PSObject.Properties | Where-Object { `$_.Name -notin @('PSPath','PSParentPath','PSChildName','PSDrive','PSProvider') }) {
                `$valName = `$prop.Name
                `$valData = `$prop.Value
                `$valType = (Get-ItemPropertyValue -Path `$Key -Name `$valName -ErrorAction SilentlyContinue | Get-Member -MemberType Property).TypeName
                # 适配不同值类型的PowerShell语法
                switch (`$valType) {
                    'String' { `$valData = "`"`$valData`"" }
                    'Int32' {}
                    'UInt32' {}
                    'ByteArray' {
                        `$valData = '@(' + (`$valData -join ', ') + ')'
                        `$valType = 'Binary'
                    }
                    default { `$valType = 'String' }
                }
                `$output += "`$indentStrSet-ItemProperty -Path `$Key -Name '$valName' -Value `$valData -Type `$valType -Force"
            }
        }
        # 递归导出子键
        foreach (`$subKey in Get-ChildItem -Path `$Key -ErrorAction SilentlyContinue) {
            `$output += Export-RegToPS -Key `$subKey.PSPath -Indent (`$Indent + 1)
        }
        return `$output
    }
    `$scriptContent = Export-RegToPS -Key `$KeyPath -Indent 0
    `$scriptContent | Out-File -FilePath `$OutputPath -Encoding utf8
    Write-Host "脚本已生成：" `$OutputPath
}"
"@

执行完成后，打开注册表编辑器右键任意分支，就能看到新增的选项。点击后会在当前PowerShell的工作目录生成以分支名称命名的PS导入脚本，脚本包含创建子键、设置所有键值的完整逻辑。

方法2：临时转换.reg文件为PS脚本 #

如果不想添加右键菜单，可先将目标分支导出为.reg文件，再用以下脚本转换成PowerShell导入脚本：

# 替换为你的.reg文件路径和输出PS脚本路径
$regFilePath = "C:\temp\exported.reg"
$psFilePath = "C:\temp\reg_import.ps1"

$regContent = Get-Content $regFilePath -Raw
$psContent = @()
$currentKey = $null

# 逐行解析.reg文件内容
$regContent -split "`r`n" | ForEach-Object {
    $line = $_.Trim()
    if ($line -match '^\[(.*)\]$') {
        $currentKey = $matches[1]
        $psContent += "if (-not (Test-Path '$currentKey')) { New-Item -Path '$currentKey' -Force | Out-Null }"
    }
    elseif ($line -match '^"([^"]+)"=(.*)$' -and $currentKey) {
        $valName = $matches[1]
        $valData = $matches[2]
        $valType = 'String'
        # 处理不同值类型的转换
        if ($valData -match '^dword:(.*)$') {
            $valData = [uint32]$matches[1]
            $valType = 'DWord'
        }
        elseif ($valData -match '^hex:(.*)$') {
            $valData = '@(' + ($matches[1] -split ',' | ForEach-Object { "0x$_" }) -join ', ' + ')'
            $valType = 'Binary'
        }
        elseif ($valData -match '^hex\(7\):(.*)$') {
            $bytes = [byte[]]($matches[1] -split ',' | ForEach-Object { [byte]"0x$_" })
            $valData = "`"$( [System.Text.Encoding]::Unicode.GetString($bytes) )`""
        }
        $psContent += "Set-ItemProperty -Path '$currentKey' -Name '$valName' -Value $valData -Type $valType -Force"
    }
}

$psContent | Out-File -FilePath $psFilePath -Encoding utf8

替换路径后运行脚本，即可得到可直接执行的PowerShell导入脚本。
