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.

There is a new requirement in 1.5.1.11 that wasn't there in 1.4.5.

It has nothing to do with unblocking the file downloaded from the Internet.

I have both zip files above and the later one stops PS 2.0 from working due to reference to a function that is not available in PS 2.0.

This line in the PSWindowsUpdate.psm1 later (1.5.1.11) file:

Get-ChildItem -Path $PSScriptRoot | Unblock-File

The "Unblock-File" function is not available in PS 2.0.

Actually PowerShell V2 is no longer supported.  Windows 2003 is out of support. 

Did you realize that it is already almost 2016.  We are no using PowerShell V5 (WMF 5).  Even my car is les than ten years old.

How can we help you live with this problem.  Would you like us to call the author and ask for a refund for you. 

You can always ask Microsoft Support to help you.  I can alos recommend some great and very inexpensive Apple systems which surely willnot have this issue.
