 # taskbarhider
 
-Small C++ program to hide/show the Windows Taskbar using the Windows API. It simply toggles between showing the taskbar or not and attempts to work against multiple monitors.
+An example of a small C++ program to hide/show the Windows Taskbar using the Windows API. By default it will toggle between showing and hiding the taskbar on monitors each time it is executed
 
-Seemed to work consistently with Windows 7 and 10. Windows 11 seems to try and recover the main monitor taskbar automatically (as of testing March 2024).
+To force it to try and show or hide the taskbar, execute with the `-show` or `-hide` flags.
+
+This is likely not the best method to accomplish the task of hiding the taskbar UI elements in most production cases, but it is a simple example of how it can still be forced through the old 32-bit Windows APIs. Previously this was tested with 1-2 monitors on Windows 7 and 10. A workaround was added (March 2024) for Windows 11 as well.
