如何使用PowerShell设置二进制注册表值（REG_BINARY）？

如何使用 PowerShell 设置二进制注册表值 (REG_BINARY)？

背景：

我需要使用 PowerShell 脚本更改 ASP.NET State 服务的一些属性。不幸的是，内置的 PowerShell cmdlet 

Set-Service
只能让您修改服务描述、启动类型、显示名称和状态。我需要修改“恢复”选项卡上的 
Subsequent failures
属性（查看服务的属性时）。我发现这个值作为 REG_BINARY 值存储在注册表中。

值的导出如下所示：

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\aspnet_state]
"FailureActions"=hex:50,33,01,00,00,00,00,00,00,00,00,00,03,00,00,00,0e,00,00,\
  00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00

在 Powershell 中，有一个 

Set-ItemProperty
cmdlet，您可以使用它来设置注册表值。对于字符串或双字值，您可以仅传递字符串或整数。我知道要更改数组中的哪个十六进制值，但我不知道如何设置二进制值。

以下行为您提供了如何创建一个示例

New-ItemProperty -Path . -Name Test -PropertyType Binary -Value ([byte[]](0x30,0x31,0xFF))

以及如何更改现有的：

Set-ItemProperty -Path . -Name Test -Value ([byte[]](0x33,0x32,0xFF))

这篇文章帮助我解决了类似的问题。谢谢！

将 xBr0k3n 和 Howard 的答案放在一起：

#Change these three to match up to the extracted registry data and run as Admin
$YourInput = "50,33,01,00,00,00,00,00,00,00,00,00,03,00,00,00,0e,00,00,00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00"
$RegPath   = 'HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\aspnet_state'
$AttrName  = "FailureActions"

$hexified = $YourInput.Split(',') | % { "0x$_"}
New-ItemProperty -Path $RegPath -Name $AttrName -PropertyType Binary -Value ([byte[]]$hexified)

只有我觉得这错过了这个问题的主要部分吗？

你会如何改变原来的：

50,33,01,00,00,00,00,00,00,00,00,00,03,00,00,00,0e,00,00,\
00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00

转换为如下格式：

([byte[]](0x33,0x32,0xFF))

编辑：在尝试使其正常工作后，结果发现您只需在所有对上添加“0x”前缀即可。不知道为什么答案中没有提到这一点。所以只需将上面的内容更改为：

0x50,0x33,0x01,0x00,0x00,0x00,0x00,0x00... etc.

然后将其包含在以下内容中：

([byte[]](0x50,0x33,0x01,0x00,0x00,0x00,0x00,0x00... etc.))

复活这个。

以下是如何在易于遵循的 powershell 中简洁地修改注册表项二进制值的方法。在此示例中，

DefaultConnectionSettings
是我们尝试修改的具有 
REG_BINARY
值的注册表项。

$path = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections"
$objName = "DefaultConnectionSettings"
$getObj = Get-ItemProperty -path $path -name $objName
$getObj.DefaultConnectionSettings[8] = 1
$objValue = $getObj.DefaultConnectionSettings
Set-ItemProperty -path $path -name $objName -Value $objValue

当您将 

Get-ItemProperty
用于具有 REG_BINARY 值的注册表项时，它会在 collection 中为您提供许多子对象。

通过引用项目的名称（在本例中我们使用 

getObj.DefaultConnectionSettings
）作为 getObj 的子对象，我们得到一个值的 array，其中每个二进制值（即 
50,33,01,00,00,00,00,00,04
）在数组。

因为它是一个数组，所以我们可以通过执行 

$getObj.DefaultConnectionSettings[8] = 1
或任何您想要代替 8 的数字来轻松引用、修改和迭代它。8 指的是数组中值的位置。在 
50,33,01,00,00,00,00,00,04
的示例中，第 9 个位置是 
04
。 请记住，与其他事物一样，数组从 0 开始计数。

设置它 

= 1
会将二进制文件中的 
04
值更改为 
01
，同时使数组中的其余值保持不变。

最后，我们使用 

Set-ItemProperty -path $path -name $objName -Value $objValue

将更改设置到位

希望这对其他人有帮助。

仅供参考，您还可以使用 PSRemoteRegistry PowerShell 模块设置二进制值（ http://psremoteregistry.codeplex.com/），在本地或远程计算机上。

$Key = 'SOFTWARE\MyCompany'     
Set-RegBinary -Hive LocalMachine -ComputerName Server1 -Key $Key -Value RegBinary -Data @([char[]]'PowerShell')

让我们从一个整数开始：

$int = 0xffffffff

获取字节：

$bytes = [bitconverter]::GetBytes($int)

将 set-itemproperty 与鲜为人知的“-type”参数一起使用，该参数可与注册表路径一起使用：

Set-ItemProperty hkcu:\key1 bin1 $bytes -type binary

拿回来：

$bytes = Get-ItemProperty hkcu:\key1 bin1 | % bin1

将4个字节转为int：

$int = [bitconverter]::toint32($bytes, 0)

'0x{0:x}' -f $int
0xffffffff

我对其他解决方案有疑问，以下是我发现有效的解决方案：

简短回答：

New-ItemProperty -path $path -name $name -value [byte]0x00,0x01,0x02 -PropertyType Binary

完整示例：

$path = "HKCU:\Software\Hex-Rays\"
$name = "StrWinStringTypes"
$value = [byte]0x00,0x01,0x02

#if key path found, just add/modify the value/data pair
If (Test-Path($path))
{
    New-ItemProperty -path $path -name $name -value $value -PropertyType Binary -Force | Out-Null
}

#if key path not found, create it first before adding value/data
Else
{
    New-Item -path $path -force
    New-ItemProperty -path $path -name $name -value $value -PropertyType Binary -Force | Out-Null
}

我已经能够编写第一个注册表项了。现在我在处理十六进制值时遇到了麻烦：
