Win7 安装.net framework 4.0 失败，错误HRESULT 0xc8000222解决办法

之前装Viusal Stuido 2010 一直失败，其实在在安装.net framework 4.0时就失败……后来就单独安装.net framework 4.0，结果还是失败，出现HRESULT 0xc8000222错误代码，

去官网上查找，发现作如下操作步骤即可

This behavior may occur if the temporary folder of Windows Update has been corrupted. We can refer to the following steps to rename this folder. Please be assured the folder will be created again when we visit the Windows Update site again.

1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.

net stop WuAuServ

2. Click Start, Run, type: %windir% and press Enter.
3. In the opened folder, rename the folder SoftwareDistribution to SDold.
4. Click Start, Run, type: cmd and press Enter.

Please run the following command in the opened window.

net start WuAuServ

原来这个还和Windows Update有关系，给目录名重命名一下再次安装，即安装成功了！
