GdMail – When we just install the Windows 10 OS, we have to install many applications so that our computer or laptop can run as it should, for example, hardware drivers, antivirus, microsoft office, and we shouldn’t miss .Net Framework 3.5, .Net Framework 4 and so on.
Unlike previous versions of Windows, in Windows 10 we are required to install everything online using the system provided by the OS. Indeed, the process is easy, we don’t need to download the manual one by one but there is a drawback, namely the process that takes a long time because the connection must be really stable.

What is Net Framework 3.5?
The Net Framework is a collection of libraries needed for various applications and games. The components in The Net Framework are one of the most important elements, because without the .NET Framework some applications cannot run.
Usually The Net Framework is Coupled with The C++ runtime.
First Solution
This first method is the most commonly used method, namely with the CMD command. All you need is a windows 10 installer CD or a windows 10 .iso file.
The first steps, enter the installer CD or mount the iso file so that we know the drive letter where the installer cd is located. (eg E:).
Open a command prompt then run as administrator. The trick is to press CTRL + S, then type ‘cmd’. After the results appear right click and select run as administrator.

Now, after you click run as administrator, a black window will appear.
Here you just type the command:
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:sourcessxs /LimitAccess
*The letters in E underline you match your Windows installation storage disk
After that, the offline .Net Framework 3.5 installation process will begin, we just have to wait for it to finish.

When finished, you can restart your computer or laptop.
Second Solution
Sometimes there is an incomplete Windows 10 installer cd or .iso file, aka there is no SXS folder in it. If so, of course we can’t use the first method, but don’t worry because we can change the location of the folder, here the admin provides a download link for the sxs folder that has the .net Framework 3.5.
Download according to your OS version.
After the download is complete, extract the downloaded file to drive C: or D: and run cmd as in the first method, just change the drive letter according to the location we just extracted.
Third Solution
If you think that the method above is still difficult, you can use the Net Framework Installer application. How to download the application here:
Run Net-Framework-Offline-Installer-v4.8.exe

Select the location of your Windows 10 installer cd or the drive mount iso, if the sxs folder is there then the words (found) will appear below it. then click Install.
This Method is very easy for those of you who don’t want to use cmd.
*Note, please turn off your antivirus first because it will usually detect a false alarm.
