Getting error while trying to run "Login-AzureRmAccount" from powershell

I am getting the error below while trying to login to azure using the power shell

PS C:\WINDOWS\system32> Login-AzureRmAccount
Login-AzureRmAccount : The term 'Login-AzureRmAccount' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is
correct and try again.

+ ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Login-AzureRmAccount:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException


PS C:\WINDOWS\system32>


In order to fix this I have done the installation of required module and it has started working fine.

PS C:\WINDOWS\system32> Install-Module -Name AzureRM -AllowClobber

PS C:\WINDOWS\system32>


But then I started getting another error:

PS C:\WINDOWS\system32> Login-AzureRmAccount
Login-AzureRmAccount : The 'Login-AzureRmAccount' command was found in the module 'AzureRM.profile', but the module could not be loaded. For more information, run 'Import-Module AzureRM.profile'.

    + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule


PS C:\WINDOWS\system32>

Then another one :-( 

PS C:\WINDOWS\system32> Import-Module AzureRM.profile
Import-Module : File C:\Program Files\WindowsPowerShell\Modules\AzureRM.profile\5.8.2\AzureRM.Profile.psm1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies

    + CategoryInfo          : SecurityError: (:) [Import-Module], PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess,Microsoft.PowerShell.Commands.ImportModuleCommand

PS C:\WINDOWS\system32>

The I had to install the module 

PS C:\WINDOWS\system32> Install-Module -Name AzureRM.profile

PS C:\WINDOWS\system32>

Finally noticed that the execution policy is set to Restricted and it should be Unrestricted.


PS C:\WINDOWS\system32> Get-ExecutionPolicy
Restricted

PS C:\WINDOWS\system32> set-executionpolicy Unrestricted

PS C:\WINDOWS\system32>


PS C:\WINDOWS\system32> Get-ExecutionPolicy
Unrestricted

PS C:\WINDOWS\system32>

and there we go the azure login script is working now.


PS C:\WINDOWS\system32> Login-AzureRmAccount
