Greetings from Windows PowerSell SDK

 

This is what happened when I first launched PowerShell after installing the SDK and .NET framework 3.

Does the installation tampers PowerShell core files? Why? What's wrong?

I restarted PowerShell and the error showed up again, Hmm.. I need to find out what went wrong, which cmdlet deals with execution restrictions...ahhhh...hmmm...right...
Get-ExecutionPolicy!  So I run it:

PS C:\Scripts> Get-ExecutionPolicy
AllSigned

 

It seems that the SDK setup process reverts PowerShell excecution policy back to its default "out-of-the-box" state - AllSigned, which means only scripts that were digitally signed can execute. 

PS C:\Scripts> Set-ExecutionPolicy RemoteSigned
PS C:\Scripts>

Restarted, and the message has gone.
