Instead of searching for a "free download" of the CAB file, the safest way to get .NET Framework 3.5 is to use the official Windows ISO.

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.
