Multistring-valued registry entries are relatively rare in the registry. The Registry Provider does, however, provide the SetMultiStringValue method to enable you to create these entries as needed. Because a multistring can store a list of strings, the SetMultiStringValue method accepts an array of strings as the parameter that determines the values of the entry.
Note that if you use the SetMultiStringValue method to append to an existing multistring-valued entry rather than create a new one, you have to first use the GetMultiStringValue method to retrieve the existing list of strings. This is because SetMultiStringValue overwrites any existing value.
The Configure Desktop Module PowerShell sample configures Windows Explorer settings, Internet Explorer download and Internet Explorer home pages.
The following VBScript code example shows how to write an array of new values to the REG_MULTI_SZ value that is located in HKEY_LOCAL_MACHINE\SOFTWARE\NewKey\MultiValueName.

Syntax
uint32 SetMultiStringValue(
[in] uint32 hDefKey = HKEY_LOCAL_MACHINE,
[in] string sSubKeyName,
[in] string sValueName,
[in] Variant sValue[] =
);
Parameters
| Name | Type | Description |
|---|---|---|
| hDefKey | UInt32 | Optional parameter that specifies the tree that contains the sSubKeyName path. The default value is HKEY_LOCAL_MACHINE (0x80000002). The following trees are defined in Winreg.h: HKEY_CLASSES_ROOT (0x80000000) HKEY_CURRENT_USER (0x80000001) HKEY_LOCAL_MACHINE (0x80000002) HKEY_USERS (0x80000003) HKEY_CURRENT_CONFIG (0x80000005) HKEY_DYN_DATA (0x80000006) Note that HKEY_DYN_DATA is a valid tree for Windows 95 and Windows 98 computers only. |
| sSubKeyName | String | Specifies the key that contains the named value to be set. |
| sValue | String | Specifies an array of string data values. |
| sValueName | String | Specifies the named value whose data value you are setting. You can specify an existing named value (update) or a new named value (create). Specify an empty string to set the data value for the default named value. |

Requirements
To use StdRegProv, the following requirements apply:
PowerShell
Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.
If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.
Operating System
StdRegProv was introduced on clients with Windows Vista and on servers with Windows Server 2008.
Namespace
StdRegProv lives in the Namespace Root/CIMv2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.
Implementation
StdRegProv is implemented in Stdprov.dll and defined in RegEvent.mof. Both files are located in the folder C:\Windows\system32\wbem:
explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\RegEvent.mof
