笔记本上上使用的SSD硬盘，空间比较小，以前安装visual studio占用空间比较大，后来直接使用官方的卸载工具，但是却遗留了很多相关的组件无法卸载。今天实在无法忍受了，发现github上有一个软件可以卸载，虽然软件针对的版本比较老，但是使用确实可以卸载干净，记录一下。
下载TotalUninstaller.zip(https://github.com/Microsoft/VisualStudioUninstaller/releases)
解压并用管理员方式运行Setup.forcedunstall.exe
键入“Y”卸载，卸载完成会自动关闭
由于本人笔记本积弊已久，安装过多个版本的visual studio，多执行几次就可以卸载完全了。
