Quickly install. NET 3.5 after reloading the system

After every reloading system (Windows 8.1 and Windows 10), one of the most frustrating things I've got is the configuration of a lot of software. Normally I'll install SQL Server, put my computer in the workgroup to set up visual Studio, then run to class or study, then come back and install it, then set up Adobe's software and some other small applications (such as QQ, input method, etc.). But there's a problem: there's always a moment to go to class, and the SQL Server installation prompt is missing. NET 3.5, which is very painful, how to install it quickly?

I've browsed through a number of ways online:

First: Install with Windows Update networking by using the Windows feature interface to check the. NET Framework 3.5 and then determine that the installation is downloaded by the system.

But this has often prompted a mistake and then failed (Microsoft's note: The Windows Update Service has a bit of a problem), this has the occasional, can not say when the problem;

The second approach: install using the standalone. NET Framework 3.5 installation package, but this also sometimes encounters the problem above;

The third method: Use the CMD command-line prompt (This method has not encountered a failure so far):

First step: Load the corresponding version of the current system image to the virtual optical drive (Windows 8.1+ can be loaded using Windows Explorer);

Second step: Run cmd as Administrator (press Win + X, then select "command line prompt (Administrator)", or press A in the English input state);

Step Three: Enter:

　　　　Dism/online/enable-feature/featurename:netfx3/source:{}:\sources\sxs or

Dism.exe/online/enable-feature/featurename:netfx3/source:{}:\sources\sxs

{} means to load the installation image of the drive letter, such as g/h/i, and so on, the above two lines of any line modified {} tag content, copied to the Clipboard, paste into the cmd window (Windows 10 directly right click on it), and then enter;

Wait for the progress bar to load to 100%, prompt:

　　　　Deployment Image Servicing and Management tool

Version:{xxxx}

Image Version: {xxxx}

Enabling feature (s)

[==========================100.0%==========================]

The operation completed successfully.

({xxxx} is the corresponding version number), close the cmd command line prompt window, go back to the location shown, tick the. NET Framework 3.5 and then OK;

To save time, I usually use this third method because it saves time and has a higher success rate.

In addition, for ASP. NET development configuration, write this memo: first install SQL Server, then install Visual Studio, and, Chinese system installed Chinese SQL Server, English language, so as not to install.
