This powershell module, as described on this page:

Windows Update PowerShell Module

Actually MUST have PowerShell 3.0

The pre-requisites are wrong, it says that only PowerShell 2.0 is required.

There is a call to an "Ublock" function, but that was first available in PS 3.0.

You should post your comment in the Q&A of that gallery item.  This forum does not maintain that content - the author of the upload does.

The module was written on Windows 2.0.  Unblocking of files is available on all versions of Windows since Vista.

Perhaps you should go back and read the instructions more carefully.  Believe me.  I have been using this since Michael wrote the first version.

HINT:  Unblock the ZIP file before you extract it.
