The Microsoft Update Catalog is an official Microsoft website that hosts standalone update packages. To find your exact CAB file:
Important Note: Microsoft changes download links frequently. Instead of providing a broken direct URL, we instruct you to use the Update Catalog. As of 2025, a direct link is not static.
Use the official DISM command with your own Windows installation media – it's the only guaranteed safe and working method. Do not download CAB files from random "free download" sites.
While many sites claim to offer a "free link" for the microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab file, downloading random CAB files from third-party sources is a significant security risk. These files often serve as the foundation for .NET Framework 3.5, which is essential for running older software on modern Windows systems.
The safest and most reliable way to get this package is directly from Microsoft or your official Windows installation media. What is the NetFx3 On-Demand Package?
This specific CAB file is the payload for .NET Framework 3.5 (which includes .NET 2.0 and 3.0). Windows 10 and 11 don't install this by default to save space, instead offering it as a "Feature on Demand." Method 1: The Recommended "Free" Way (Windows Features)
Before hunting for a download link, try the built-in method. It downloads the necessary files directly from Windows Update. Press Win + R, type optionalfeatures.exe, and hit Enter.
Check the box for .NET Framework 3.5 (includes .NET 2.0 and 3.0).
Click OK and select Let Windows Update download the files for you. Method 2: Using Your Windows ISO (No Internet Needed)
If you are offline or getting errors like 0x800F0906, you can extract the CAB file from a Windows ISO.
Mount your Windows ISO (right-click the file and select Mount). Note the drive letter (e.g., D:). Navigate to D:\sources\sxs.
You will see the file microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab right there.
To install it, open Command Prompt as Administrator and run:Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess Method 3: Official Microsoft Download Center
If you need the installer for a different environment, use the official .NET Framework 3.5 Service Pack 1 (Full Package) available on the Microsoft website. This is the only "link" you should trust to avoid malware. Why Avoid Third-Party "Free Download" Links?
Malware Injection: CAB files can be tampered with to include backdoors.
Version Mismatch: Using a CAB file from a different Windows build (e.g., trying to use a Windows 1809 file on a 22H2 system) can cause system instability or "Assembly not found" errors.
Corrupt Files: Unofficial mirrors often host incomplete files that fail during the DISM injection process.
Pro Tip: If you're a system administrator, you can also download these packages via the Volume Licensing Service Center (VLSC) or the Microsoft Evaluation Center as part of the "Languages and Optional Features" ISO.
Are you getting a specific error code like 0x800F081F while trying to install this?
Microsoft does not host this CAB file on a simple “click to download” public webpage for consumers. Instead, you can obtain it through three official channels.
From the ISO, the file is at: D:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab
You can copy it from there to your desktop. But again – it’s tied to that specific Windows build.
Microsoft provides the ADK for free. Within the installation media, you can extract the necessary FOD (Features on Demand) CAB files.
(Replace D: with your actual mounted drive letter.)
This extracts and installs the official Microsoft CAB without needing a separate download link.
Warning: Do not download .cab files from random "free download" sites, forums, or file-hosting services (e.g., mediafire, mega, rapidshare links posted by users).
If you downloaded from a third-party site, delete it immediately and use the ISO method. The genuine Microsoft CAB file is never flagged by legitimate antivirus software.
