Install every Pending Windows Update
One reason that might trigger the 0x800F0950error when you’re attempting to install the .NET Framework 3.5 update is the fact that Windows Update already has a scheduled update ready to do the same thing.
Some users encountering the same error code have reported that they finally managed to fix the issue after they updated their Windows 10 / 11 version to the latest build available. After doing this and restarting their computer, most have reported that .NET Framework 3.5 was already installed so there was no need to use the dedicated installer.
Note: The instructions on installing any pending updates are identical on both Windows versions.
