说明这些软件是绿色版或者重装过系统，可以在软件根目录内找到该软件的卸载文件进行卸载，具体操作方法如下：
所需材料：WIN7系统演示。
一、这里以WIN7系统和百度网盘为例，首先右键点击软件快捷方式，菜单内点击“打开文件位置”。

二、进入文件目录后，点击右上角搜索栏，输入“uninst”。

https://iknow-pic.cdn.bcebos.com/0d338744ebf81a4c4182f4c6d82a6059252da608"/>
三、搜索的结果内双击打开“uninst.exe”（一般软件卸载文件名就是uninst.exe，还有一些叫作Uninstall.exe，所以搜索时只搜索前面的uninst即可找出）。

四、这时就可以打开该软件的卸载文件进行手动卸载了。
