+# Old Explorer Commands
+This mod makes the following commands in This PC, which are normally hardcoded to open Settings, open Control Panel instead.
+- Open Settings
+- System properties
+- Uninstall or change a program
+
+# !!IMPORTANT!!
+
+Beginning with Iron (Windows Server 2022), a redirect from the System page to Settings is **hardcoded** into `ExplorerFrame.dll`.
+As such, this mod will not work on Windows Server 2022, Windows 11, or greater to restore the old System page unless a modification
+to `ExplorerFrame.dll` takes place to remove the redirect.
