+# 🧠 Sysnative Usage in 32-bit Scripts on 64-bit Windows
+
+This script demonstrates how to correctly call **64-bit system executables** from a **32-bit process**, using the special Windows path alias: `Sysnative`.
+
+---
+
+## 🧩 Why Use `Sysnative`?
+
+When a 32-bit process runs on a 64-bit Windows system, Windows **redirects** calls to `System32` to `SysWOW64`, which contains 32-bit versions of executables.
+
+To access the **actual 64-bit system files** from a 32-bit context (like in a 32-bit CMD or installer), you must use `Sysnative`.
+
+---
+
+## ⚙️ What This Script Does
+
+It checks if the script is running in a 32-bit context on a 64-bit system:
+
+```bat
+if defined PROCESSOR_ARCHITEW6432
+Set cmdreg=%SystemRoot%\sysnative\reg.exe
+Set cmdpowershell=%SystemRoot%\sysnative\WindowsPowerShell\v1.0\powershell.exe
+Set cmddism=%SystemRoot%\Sysnative\cmd.exe /c Dism
+...
+```
+These variables are then used to:
+
+- Modify registry keys with 64-bit reg.exe
+- Run 64-bit PowerShell scripts
+- Install drivers with 64-bit DISM
+- Change power settings, run wusa, etc.
+
+📘 **Tip**
+
+Only use `Sysnative` when running 32-bit scripts on 64-bit Windows.  
+If your script runs in a 64-bit context, `System32` already points to the correct location.
