WIndows 7 安裝vs2012提示.net framework 4.0 失敗

WIndows 7 安裝.net framework 4.0 失敗，錯誤HRESULT 0xc8000222解決辦法

以前裝Viusal Stuido 2010 Ultim一直失敗，並且等的時間特別長，在安裝.net framework 4.0時就失敗……

後來就單獨安裝.net framework 4.0，結果仍是失敗，出現HRESULT 0xc8000222錯誤代碼，

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

原來這個還和Windows Update有關係，給目錄名重命名一下再次安裝，即安裝成功了！
