To confirm installation, run the following PowerShell command:

Get-WindowsOptionalFeature -Online -FeatureName NetFx3

The State should show “Enabled”.

After extraction, you can install .NET Framework 3.5 without internet: for modern Windows 10/11 management

dism /online /enable-feature /featurename:NetFx3 /all /source:C:\NetFx3Extracted /limitaccess

Or use the extracted cab directly without extraction:

dism /online /add-package /packagepath:Microsoft-Windows-NetFx3-OnDemand-Package.cab

NetFx3 stands for .NET Framework 3.5. Many Windows applications (especially older or enterprise software) rely on .NET Framework 3.5 to run.

In modern versions of Windows (10 and 11), Microsoft uses a feature called "Features on Demand". Instead of pre-installing every optional component (which would bloat the operating system), Windows keeps the installation files (stored in a .cab or cabinet file) tucked away.

If you are determined to reclaim the disk space, you can use the DISM (Deployment Image Servicing and Management) tool.

Warning: This process involves command-line tools. Proceed with caution.

Alternatively, for modern Windows 10/11 management, you can simply use the settings menu to stop Windows from keeping these installation files handy, though this usually requires a Group Policy change to prevent Windows from re-downloading them automatically.

The “on-demand” part means Windows does not install it by default. When an app requires .NET 3.5, Windows either prompts you to download it via Windows Update or—if you point it to this CAB—installs it directly from the local file.
