Powershell小技巧之获取注册表值的类型

Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

$key = Get-Item -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

$key.GetValueNames() |
  ForEach-Object {
    $ValueName = $_

    $rv = 1 | Select-Object -Property Name, Type, Value
    $rv.Name = $ValueName
    $rv.Type = $key.GetValueKind($ValueName)
    $rv.Value = $key.GetValue($ValueName)
    $rv
  }

dir Registry::HKEY_CLASSES_ROOT\.* -name | Sort-Object

function Get-RegistryValues($key) {
                 (Get-Item $key).GetValueNames()
}

Get-RegistryValues HKLM:\Software\Microsoft\Windows\Currentversion
Get-RegistryValue读取任意注册表键值并返回其内容，完整代码如下所示：
function Get-RegistryValue($key, $value) {
                  (Get-ItemProperty $key $value).$value
}
Get-RegistryValue ' HKLM:\Software\Microsoft\Windows\Currentversion' `
SM_GamesName

function Set-RegistryValue($key, $name, $value, $type="String") {
  if ((Test-Path $key) -eq $false) { md $key | Out-Null }
       Set-ItemProperty $key $name $value -type $type
  }
   Set-RegistryValue HKCU:\Software\TestABC myValue Hello
   Set-RegistryValue HKCU:\Software\TestABC myValue 12 Dword
   Set-RegistryValue HKCU:\Software\TestABC myValue `
([Byte[]][Char[]]"Hello") Binary

function Remove-RegistryKey($key) {
Remove-Item $key -Force
}
通过Remove-ItemProperty函数删除注册表值，完整的代码如下所示：
function Remove-RegistryValue($key, $value) {
Remove-ItemProperty $key $value
}
