我在为. NETCore开发设置系统时遇到了很多麻烦。大约一年前，我在我的机器上安装了VisualStudio，但是它在很久以前就被删除了。但是它的一些残余仍然在系统中。所以当我试图重新安装最新版本的VS社区版时（2019）from https://visualstudio.microsoft.com/downloads/安装进行得很顺利，但我在启动VS 2019甚至在创建项目时收到了太多的错误和警告，因为它无法找到.NET核心SDK，然而，它们就在系统中，就像在环境变量中添加的一样。
最后我决定删除所有安装在我系统上的当前和旧的VS。并从头开始重新安装一切。这是非常困难的，因为大多数文件没有得到卸载，并给出错误，所以我使用微星库存工具https://sqlgeekspro.com/uninstall-sql/，并成功地卸载了几乎所有的东西，除了几个版本的.NET核心SDKs。我也尝试过。NET核心卸载工具https://github.com/dotnet/cli-lab/releases，但它不工作的SDK与VS一起安装，这是它的限制。
下面给出的是我需要卸载的东西，无法，x1c 0d1x
当我尝试从“添加/删除程序”卸载.NET Core SDK 3.1.201时，出现此错误。

当我试图卸载任何Visual C++时，我得到这个错误：
