Syntax
uint32 DeleteValue(
[in] uint32 hDefKey = HKEY_LOCAL_MACHINE,
[in] string sSubKeyName,
[in] string sValueName
);
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 deleted. |
| sValueName | String | Specifies the named value to be deleted from the subkey. Specify an empty string to delete the default named value (the default named value is not deleted its value is set to “value not set” |

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
