How can I uninstall a specific Windows 7 update?

My Windows 7 has automatically installed a bunch of updates that make no sense - e.g. Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 SP1 and Windows Server 2008 R2 SP1 for x64 (KB3072305) when I have .NET Framework 4.6.1. All the answers I've found on SU so far failed to work.

The update does not show up in Control Panel -> Programs and Features -> Installed Updates. Searching for the KB number there finds nothing.

wusa /uninstall /kb:3072305 fails with

Installer encountered an error: 0x800b0100

No signature was present in the subject.

Nirsoft's wul has the "uninstall" option greyed out for any update I've checked, including this one.
