Windows 10 system .NET Framework 3.5 offline installation method

Win10 technology preview version brings many new functions to users, but also brings troubles and problems to users. The .NET Framework 4.5 is pre-installed on the system, but some applications in the Win10 Technology Preview require .NET Framework 3.5 to function properly. When we double-click to open a similar application, Windows 10 Preview will remind us that we need to download and install .NET Framework 3.5 on the network, which will cause us some trouble.

However, we have a more convenient way to install it, no need to download the network, use DISM (deployment image service and management) and Win10 technology preview version of the installation image can be done. Let's take a look at the specific method below.
1. Load the image of Win10 Technology Preview. In the Win10 preview version, you can load the ISO image file by double-clicking, or you can use the soft media virtual drive in the Rubik's cube to load it conveniently;

2, right click on the Win10 start menu button, select the “Command prompt (administrator) & rdquo;, open the command prompt;

3, directly enter the following line in the command prompt, of course, you can directly paste and copy the past, remember? Win10's command prompt is now ready to use shortcuts such as “Ctrl+C”, “Ctrl+V”, and then press Enter. Note that the “D:” is the name of the drive letter where the image is installed. This needs to be modified according to the actual situation of your computer. Next you should see a progress bar. When you are done, you will be prompted to "Operation completed successfully";;
