REG ADD a REG_MULTI_SZ Multi-Line Registry Value
提问by Edwin Lee
To add a REG_MULTI_SZ multi-line registry value, i can do
要添加 REG_MULTI_SZ 多行注册表值，我可以
reg.exe ADD "HKLM\path\to\registry\key" /v RegistryValue /t REG_MULTI_SZ /d "abcreg.exe ADD "HKLM\path\to\registry\key" /v RegistryValue /t REG_MULTI_SZ /d "abcREG ADD "HKLM\LOCATION" /v "Value" /t REG_MULTI_SZ /d item1REG ADD "HKLM\LOCATION" /v "Value" /t REG_MULTI_SZ /d "item1"REG ADD "HKLM\LOCATION" /v "Value" /t REG_MULTI_SZ /d item1Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\software\harrytest]
"test"=hex(7):76,00,61,00,6c,00,75,00,65,00,31,00,00,00,76,00,61,00,6c,00,75,\
00,65,00,32,00,00,00,00,00,76,00,61,00,6c,00,75,00,65,00,34,00,00,00,76,00,\

item2@reg.exe add "HKCU\Software\Wirkomatron" /v "MySoftware" /d "Software1"##代码##"Software2"##代码##"Software3"##代码## /t REG_MULTI_SZ /f
##代码## /f
"item2" /f
item2 /f
##代码##def##代码##"
def##代码##"
which would add ("abc", "def").
这将添加（“abc”，“def”）。
But what if i need to add ("abc", "", "def"), i.e. an empty item in between?
但是如果我需要添加 ("abc", "", "def")，即中间的一个空项怎么办？

This worked for me:
这对我有用：
##代码##or if your items have whitespace:
或者如果您的项目有空格：
##代码##Make sure you don't have TWO trailing "\0" separators (one is OK, with or without the trailing \0 you will get your last return character) like the example below (like I saw in a TechNet article), or you will get an "ERROR: Invalid value specified for '/d'.":
确保您没有两个尾随“\0”分隔符（一个都可以，无论是否带有尾随 \0，您都将获得最后一个返回字符），如下例所示（就像我在 TechNet 文章中看到的那样），或者您将得到一个“错误：为‘/d’指定的无效值。”：
##代码##回答by Harry Johnston
This probably isn't possible using reg add, because the data you're trying to set is improperly formed. REG_MULTI_SZ values are terminated by an empty string, so having an empty string as part of the value is not allowed.
这可能无法使用 reg add，因为您尝试设置的数据格式不正确。REG_MULTI_SZ 值以空字符串终止，因此不允许将空字符串作为值的一部分。
If you really need to, and on the understanding that some software won't be able to read the key correctly, you could use reg import instead. For example, the following file creates a value with an empty string in the middle:
如果您确实需要，并且了解某些软件将无法正确读取密钥，则可以改用 reg import。例如，以下文件创建了一个中间带有空字符串的值：

现在您可以使用批处理脚本正确地做到这一点。

Just for reference.
仅供参考。
If you just want to insert a new line then you will need to simulate it with a space in the desire empty line. If the space would have an undesired impact in what you are trying to achieve then this post is not useful for you.
如果您只想插入一个新行，那么您需要在所需的空行中用一个空格来模拟它。如果该空间会对您尝试实现的目标产生不良影响，那么这篇文章对您没有用处。
reg.exe ADD "HKLM\path\to\registry\key" /v RegistryValue /t REG_MULTI_SZ /d "abc\0 \0def\0"
reg.exe ADD "HKLM\path\to\registry\key" /v RegistryValue /t REG_MULTI_SZ /d "abc\0 \0def\0"
