RegWrite

RegWrite is a method of the Windows Script Host (WSH) WshShell object that writes a value to the Windows Registry from scripts written in VBScript or JScript. It is commonly used to configure software, automate user-specific settings, or implement lightweight script-driven changes to the registry. The method operates on a registry path where the final segment denotes the value name, and the preceding path identifies the key.

Syntax and usage: WshShell.RegWrite strName, varValue, [strType] The strName argument specifies the full registry path to the value. The path ends with the value name, while the portion before it identifies the key (for example, HKCU\Software\Example\Setting is the value named Setting under the key HKCU\Software\Example). varValue is the data to write. The optional strType argument selects the registry data type, such as "REG_SZ", "REG_DWORD", "REG_QWORD", "REG_MULTI_SZ", "REG_BINARY", or "REG_EXPAND_SZ". If strType is omitted, RegWrite attempts to infer the type from the data provided.

Privileges and behavior: Writing to certain registry hives, such as HKEY_LOCAL_MACHINE, typically requires elevated privileges. Writes to HKEY_CURRENT_USER generally do not require administrator rights. If the target key or value cannot be created or modified due to permissions or an invalid path, RegWrite will raise an error.

Examples:

Set WshShell = CreateObject("WScript.Shell")

WshShell.RegWrite "HKCU\Software\MyCompany\MyApp\Setting", "Enabled"

WshShell.RegWrite "HKLM\Software\MyCompany\MyApp\Flags", 1, "REG_DWORD"

Related methods include RegRead and RegDelete, all part of the WshShell object for registry interaction. RegWrite provides a simple, scriptable way to persist configuration data in the Windows Registry from automation tasks.
