电脑下载完软件之后，安装好了，桌面上还有一个电脑和光盘样子的图标是什么？

The appearance of this icon could be due to unintentionally copying the original installation folder along with the software during转移 or backup processes. This folder typically holds the software's main setup file, enabling its execution on another computer when transferred to the same directory without requiring a fresh download or reinstall.

To maintain a clutter-free desktop and optimize system performance, it is advisable to retain only the software shortcut and eliminate the surplus installation package folder. For reinstallation on another device, it's ideal to directly download the latest version from the official website or a reputable source, ensuring optimal functionality and security of the software.
