Powershell cannot be loaded on Windows10

Question

I am running powershell to fetch running application. It works fine in Windows 7 but I got an error when I try to run it on Windows 10. Something about Authorization. This is the error

D:\\z.test\\getprocess.ps1 : File D:\\z.test\\getprocess.ps1 cannot be loaded. The file D:\\z.test\\getprocess.ps1 is not digitally signed. You cannot run this script on the current system. For more information about running scripts and setting execution policy, see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170 . At line:1 char:1 + D:\\z.test\\getprocess.ps1 + ~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess

What seems to be the problem here? Please help.

Answer 1

Run PowerShell as Administrator and type:

Set-ExecutionPolicy RemoteSigned

Answer 2

Please see this technet page:

Powershell has a policy option on what scripts to run. The policy can be set to:

• Restricted - No scripts can be run. Windows PowerShell can be used only in interactive mode.
• AllSigned - Only scripts signed by a trusted publisher can be run.
• RemoteSigned - Downloaded scripts must be signed by a trusted publisher before they can be run.
• Unrestricted - No restrictions; all Windows PowerShell scripts can be run.

If you are happy to accept the security risks then run:

Set-ExecutionPolicy Unrestricted

However I recommend signing your scripts. If you have a code signing certificate then you can sign your script using the following:

$cert = Get-ChildItem cert:\CurrentUser\My\2C096472E989BA373512C307829E8E557A12BD93
Set-AuthenticodeSignature -Certificate $cert -FilePath C:\path_to_script.ps1

Replace C:\\path_to_script.ps1 with your path to your script you wish to sign and replace cert:\\CurrentUser\\My\\2C096472E989BA373512C307829E8E557A12BD93 with a path to your code signing certificate in the Windows certificate store.
