PowerShell Inline Execution

Windows PowerShell 5.1 command-line examples that execute a UTF-16LE Base64 command, download and evaluate a script string, or launch a child command through WScript.Shell. These operations run locally under the invoking process's security context. DownloadString requires outbound access to the supplied URL. Encoding and in-memory evaluation do not provide elevation, remote execution, or guaranteed detection evasion.
