PowerShell注册表操作命令总结

你可以像导航文件系统那样来访问注册表，PowerShell把文件系统和注册表都当作层次信息系统来处理。注册表中的键对应于文件系统的目录，但是键对应的值和文件系统中的文件不是非常类似。相反的，它们显示在属性栏，被以键的属性来管理。

下面的列出了访问注册表所需的所有命令。
复制代码 代码如下:
命令                 描述
Dir, Get-ChildItem 列出键的内容
Cd, Set-Location 更改当前（键）目录
HKCU:, HKLM:         预定义的两个重要注册表根目录虚拟驱动器
Get-ItemProperty 读取键的值
Set-ItemProperty 设置键的值
New-ItemProperty 给键创建一个新值
Clear-ItemProperty 删除键的值内容
Remove-ItemProperty 删除键的值
New-Item, md         创建一个新键
Remove-Item, Del 删除一个键
Test-Path         验证键是否存在

注意：注册表几乎存储了Windows的核心配置。所以这也是它为什么成为我们用来读取和更改Windows配置的重要位置。因此乱搞或者误删非常危险，可能造成Windows不能启动。
