You plan to use Windows PowerShell scripts to configure system settings when you deploy Windows 7.
You need to ensure that Windows PowerShell scripts will run on the client computers during initial setup.
What should you do? (Choose all that apply.)

A.
Use Group Policy preferences.

B.
Create a custom task sequence.

C.
Create a Group Policy object (GPO).

D.
Run the script as a standard user account.

E.
Set the script execution policy to AllSigned.

F.
Set the script execution policy to RemoteSigned.

Explanation:
As part of PowerShell’s “secure by default” initialsetup, scripts are not allowed to be ran by the command
interpreter. This behavior can be modified by changing the PowerShell execution policy.
There are four execution polices to choose from:
Restricted – the default, allows no scripts to run
AllSigned – all scripts must be Authenticode-signed to run
RemoteSigned- Scripts downloaded from a remote location must be signed
Unrestricted- PowerShell will run any script, works like what you are probably used to now
