+# Win32 Tray Clock Experience
+This mod makes the clock button on the Windows 10 taskbar open the
+Win32 tray clock from Windows 8.1 and before instead of the XAML one
+from Windows 10 and up. This *should* work on Windows 11 with the legacy
+taskbar, but I have not tested it.
+
+Based on the ExplorerPatcher implementation.
