### Overview

**JSRT** enables control of a Windows system using the built-in **Microsoft JsRT (JavaScript Runtime)**.

Depending on the execution environment, Microsoft JsRT may be referred to as:

* `WSH`
* `Windows Scripting Host`
* `cscript`
* `jscript.dll`

On classic Windows systems, the JScript engine is implemented in **`jscript.dll`** (JScript 5.x). When running via `cscript` or `wscript`, this engine is typically used unless hosted by another environment.

This skill generates and executes a **single `.js` file** that interacts with Windows using COM objects and built-in scripting capabilities.

## Execution Flow

1. Create a **single JavaScript file** using all references described in this document.
2. Perform Windows operations using COM objects.
3. Execute the script:

```cmd
cscript YOUR_JS_FILE.js
```

## Available Windows Capabilities

### 1. File System Access

COM objects:

* `Scripting.FileSystemObject`
* `ADODB.Stream`

Typical usage:

* Reading and writing files
* Creating and deleting directories
* Handling text or binary streams

---

### 2. System & Runtime Information

COM objects and functions:

* `WScript.Shell`
* `WbemScripting.SWbemLocator`
* `GetObject`

Example:

```js
GetObject("winmgmts:{impersonationLevel=impersonate}!\\\\"
          + this.computer + "\\" + this.namespace);
```

Use cases:

* Executing Windows shell commands
* Querying WMI
* Retrieving system configuration
* Accessing environment variables

---

### 3. HTTP Communication

Possible COM objects (availability depends on installed MSXML/WinHTTP components):

* `Microsoft.XMLHTTP`
* `WinHttp.WinHttpRequest.5.1`
* `Msxml3.XMLHTTP`
* `Msxml2.XMLHTTP`
* `Msxml2.XMLHTTP.7.0`
* `Msxml2.XMLHTTP.6.0`
* `Msxml2.XMLHTTP.5.0`
* `Msxml2.XMLHTTP.4.0`
* `Msxml2.XMLHTTP.3.0`
* `Msxml2.XMLHTTP.2.6`
* `Msxml2.ServerXMLHTTP`
* `Msxml2.ServerXMLHTTP.6.0`
* `Msxml2.ServerXMLHTTP.5.0`
* `Msxml2.ServerXMLHTTP.4.0`
* `Msxml2.ServerXMLHTTP.3.0`
