During general installation, the desktop will automatically generate shortcut keys. If not, find the folder where the application is installed, find the program file with the exe extension in it, usually the icon of that application, and then right-click to select the shortcut and send it to the desktop. You can try to find relevant folders through search, and then create shortcuts on the desktop.
Extended answer: Because there are no shortcuts on the desktop, you can take them out of the file and put them on the desktop.
According to your installation path, you can go to the software installation package, find the icon of the software in it, and then right-click to select send shortcut to the desktop.
