The desktop is the C drive of the system. If you install the software on the desktop, there will be more things in your system disk space. The capacity will become smaller, which will slow down the boot time. When installing, you can choose the path in other disks. After the installation is completed, you will generally be prompted to ask if you want to create a path on the desktop. Tick it and you will be OK. In this way, the shortcut of the software you just installed will appear on the desktop without occupying your system disk.
