I can't update Windows 8.1 in audit mode

If you are preparing a custom install of Windows 8.1, you could find a problem with the download the updates in audit mode. I've been researching and it seem to me that if you don't activate Windows 8.1 you can't update Windows. This don't kwow if it will change in the future. This is today. 

Looking in Technet, I found a interesting solution. You can invoke the updates from PowerShell. Is a easy process. 

1. You can download the scripts package from here.

2. Decompress the package and copy the folder in these paths:

C:\Windows\System32\WindowsPowerShell\v1.0\Modules C:\Windows\SysWOW64\WindowsPowerShell\V1.0\Modules

3. Run PowerShell ISE as administrator.

4. Introduce the following instructions without quotes:

"Set-ExecutionPolicy RemoteSigned"

"Import-Module PSWindowsUpdate"

"Get-WUInstall"

5. Then you need to restart the computer.

Later it activate Restricted Mode of Set-ExecutionPolicy.
