Visual Studio 2013/15 Nuget Errors on Console - "The module to process 'nuget.psm1', listed in field 'ModuleToProcess' of module manifest..."

Question

Opening up Nuget Console I receive the following error:

I can update some of the nuget packages but not Entity Framework and some other packages. With the latter I receive an error:

"...failed to initialize the PowerShell host. If your PowerShell execution policy setting is set to AllSigned, open the Package Manager Console to initialize the host first."

I should add I have Windows 8.1 Pro 64 bit.

This explains how to resolve part of my issue (but no why it had happened): http://social.msdn.microsoft.com/Forums/en-US/0b20e64e-e35f-4d0e-91f1-aebcfda7ebf2/package-manager-console-failed-to-load?forum=visualstudiogeneral

So edit devenv.exe.config and add the following (you may not need the "runtime" nor "assemblyBinding" tags but you get the idea:

 <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="System.Management.Automation" publicKeyToken="31bf3856ad364e35" />
            <publisherPolicy apply="no" />
          </dependentAssembly>
        <dependentAssembly>
          <assemblyIdentity name="Microsoft.PowerShell.Commands.Utility" publicKeyToken="31bf3856ad364e35" />
          <publisherPolicy apply="no" />
        </dependentAssembly>
        <dependentAssembly>
          <assemblyIdentity name="Microsoft.PowerShell.ConsoleHost" publicKeyToken="31bf3856ad364e35" />
          <publisherPolicy apply="no" />
        </dependentAssembly>
        <dependentAssembly>
          <assemblyIdentity name="Microsoft.PowerShell.Commands.Management" publicKeyToken="31bf3856ad364e35" />
          <publisherPolicy apply="no" />
        </dependentAssembly>
        <dependentAssembly>
          <assemblyIdentity name="Microsoft.PowerShell.Security" publicKeyToken="31bf3856ad364e35" />
          <publisherPolicy apply="no" />
        </dependentAssembly>
        <dependentAssembly>
          <assemblyIdentity name="Microsoft.PowerShell.Commands.Diagnostics" publicKeyToken="31bf3856ad364e35" />
          <publisherPolicy apply="no" />
        </dependentAssembly>
        </assemblyBinding>
    </runtime>

Now this resolves my issue of not being able to update NuGet packages. However I still see errors i.e.:

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\WINDOWS\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(32) : Error in type "System.Xml.XmlNode": Exception: Cannot create a code method because of the method format. The method should be public, static, and have one parameter of type PSObject.

Bottom line I must have screwed up my Windows 8.1 Pro permissions. I was trying to open up links within Visual Studio 2013 into Chrome so I installed Chrome as administrator... the rest is history.

If I had time I would reinstall Windows 8.1 but the aforementioned temp solution is just that... a temp solution.

I found no windows "fix" and no-one appears to have had the same issue.

Hope this sort of helps anyone else.
