My first Windows PowerShell (WPS) script, essentially, “Hello World”, results in the following

File E:\hello.ps1 cannot be loaded because the 
      execution of scripts is disabled on this system. 
Please see "get-help about_signing" for more details.

Whee. This is security mechanism, but it’s probably not what you want by default. Instead, open PowerShell and execute:

Set-ExecutionPolicy RemoteSigned

There is also the PowerShell Community Extensions resource for useful third-party cmdlets.
