Windows处理dism mount残留

Windows处理dism mount残留

背景：使用uupdump下载ISO过程中可能各种原因中途失败，会有dism mount残留，如何处理这些残留很关键，否则后面没法正常使用uupdump下载ISO，或者dism命令使用出现异常。

查看dism mount 残留的powershell如下

# 定义注册表路径
$regPath = "HKLM:\SOFTWARE\Microsoft\WIMMount\Mounted Images"

# 使用Get-ChildItem递归遍历注册表项
Get-ChildItem -Path $regPath -Recurse | ForEach-Object {
    # 获取当前项的所有子项
    $subKeys = Get-ItemProperty -Path $_.PSPath -ame * -ErrorAction SilentlyContinue
    
    # 检查是否存在名为"Mount Path"的子项
    if ($subKeys.PSObject.Properties.ame -contains "Mount Path") {
        # 输出到的"Mount Path"值
        $mountPathValue = $subKeys."Mount Path"
        Write-Output "Found 'Mount Path' with value '$mountPathValue' at key '$($_.PSPath)'"
        $mountPathValue
        Write-Output ""
    }
}

会显示目录Path

比如有多个

E:\MountUUP

C:\$WinREAgent\Scratch\Mount

则执行

Dism /Unmount-Image /MountDir:"E:\MountUUP" /Discard

Dism /Unmount-Image /MountDir:"C:\$WinREAgent\Scratch\Mount" /Discard
