+# Remove Windows Spotlight Desktop Shortcut
+This mod removes the new Spotlight shortcut that appears on the desktop when you use Spotlight wallpaper mode.
+Works on latest Windows 10 and LTSC 2021. Windows 11 has not been fully tested yet.
+
+## Post-Install instructions
+After installing the mod, you could either restart the explorer.exe process or refresh your desktop using the context menu.
+This will make the icon not show up on your desktop anymore. Enjoy!
