Microsoft Windows Netfx3 Ondemand Package.cab Download Free

You do not need to download this .cab from a random website. Instead:

Only download the .cab directly if you’re an IT pro with access to Microsoft Volume Licensing or MSDN.

NetFx3 refers to Microsoft .NET Framework 3.5 (which includes .NET 2.0 and 3.0).
The “On-Demand Package” (.cab file) is a feature included in Windows 10, Windows 11, and Windows Server (2016/2019/2022) that allows installation of .NET Framework 3.5 from an alternative source—without needing Windows Update or an internet connection.

This is the easiest method and does not require downloading a standalone .cab file.

Once you have extracted the .cab from official media, install it using DISM (Deployment Imaging Service Management Tool) – built into Windows.

Step‑by‑step (run as Administrator in Command Prompt or PowerShell):

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs

(Replace D: with your mounted ISO drive letter or the folder where sxs is located)

If you copied the .cab file elsewhere:

DISM /Online /Add-Package /PackagePath:C:\temp\microsoft-windows-netfx3-ondemand-package.cab

Expected result:

  • Reboot if prompted.

    • Even with the correct .cab file, you may hit errors. Here’s how to fix them.

    Microsoft does not offer a direct public download link for the standalone .cab file on their mainstream download center. Instead, the file is embedded inside every official Windows 10/11 ISO image.

    Bottom line: Skip random download sites. Use built-in Windows methods to install .NET 3.5 – it’s already free and safer.
