Earlier, we have seen how to enable .NET Framework in Windows 10, in following article:

How to enable .NET Framework 3.5 on Windows 10

However the PowerShell method discussed in above mentioned article requires you to specify the source files using Windows 10 ISO file. But if you’ve upgraded your earlier version of Windows to Windows 10, you may not have the source files with you. In that case, you can try enabling .NET Framework via Turn Windows Features On or Off page in Control Panel. However, when we tried to enable .NET 3.5 from there, we got this message:

Windows couldn’t complete the requested changes.

Windows couldn’t find required files to complete the requested changes. Make sure you’re connected to the Internet and try again.
