win10安裝framework3.5

最近win10下載framework3.5安裝時，一直失敗，都是在下載必要原件的地方失敗，改機碼也沒用。

後來看到一招，就是找一個win server2012以上的安裝iso，把裡面的sxs資料夾複製到win10的c槽，然後用powershell執行下列指令，就成功了。

dism.exe /online /enable-feature /featurename:netfx3 /Source:c:\sxs

Recently, I kept failing to install Framework 3.5 on Windows 10. The failure always occurred at the stage of downloading the necessary components, and modifying the registry didn't help.

Later, I found a method that worked. You need to find an installation ISO for Windows Server 2012 or later, copy the "sxs" folder from the ISO to the C drive of your Windows 10 machine, and then execute the following powershell command. This solved the problem:

dism.exe /online /enable-feature /featurename:netfx3 /Source:c:\sxs
