Let’s have a look at desktop, there should be new file with HotSpot.bat and its extension will be different from normal files.
As you see, BAT file are executable command file and they need not to be installed. Also, you can see additional menu in Windows Explorer that shows Application Tools like Run as Administrator and Pin to Taskbar.
