### Description

Creates a registry key at the given path, automatically creating any missing parent keys along the way. If the key already exists, nothing happens.

### Syntax

$cs.Reg_CreateKey(string regroot, string regpath)

### Parameters

#### regroot (String)

Root hive: `HKLM`/`HKEY_LOCAL_MACHINE`, `HKCU`/`HKEY_CURRENT_USER`, or `HKU`/`HKEY_USERS`.

#### regpath (String)

Registry key path to create, relative to `regroot`. Missing parent keys are created automatically.

### Return value

None.

### Example

**PowerShell**

```powershell
$cs.Reg_CreateKey('HKLM', 'SOFTWARE\7-Zip')
```

Creating a nested vendor/product key structure to hold app-specific configuration, even though none of the parent keys exist yet.

```powershell
$cs.Reg_CreateKey('HKLM', 'SOFTWARE\Contoso\AppSuite\Licensing')
$cs.Job_WriteLog("Created Licensing configuration key")
```

Creating a per-feature subkey during `PostInstall` so later steps can write feature-specific settings into it.

```powershell
$cs.Reg_CreateKey('HKLM', 'SOFTWARE\Contoso\AppSuite\Features\Reporting')
$cs.Reg_SetDword('HKLM', 'SOFTWARE\Contoso\AppSuite\Features\Reporting', 'Enabled', 1)
```
