Error during installing PSWindows Update module - powershell

Question

I was going to automate some regular task on client computers using Powershell module. In this way, PSWINDOWSUPDATE is one of bests. But, I receive an error during install that:
PS C:\Users\stackoverflow> install-module -name pswindowsupdate -scope currentuser
PackageManagement\Install-Package : Package 'PSWindowsUpdate' failed to be installed because:
Access to the path 'C:\Users\stackoverflow\AppData\Local\Temp\ipufiq2h\PSWindowsUpdate.dll' is denied.
At C:\Program Files\WindowsPowerShell\Modules\PowerShellGet\1.0.0.1\PSModule.psm1:1809 char:21
+ ... $null = PackageManagement\Install-Package #PSBoundParameters
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidResult: (PSWindowsUpdate:String) [Install-Package], Exception
+ FullyQualifiedErrorId : Package '{0}' failed to be installed because: {1},Microsoft.PowerShell.PackageManagement
.Cmdlets.InstallPackage
running the command in administrative mode and without -scope switch didn't solve the problem.
Edit1: The problem is solved. But there is another problem. When I call import-module pswindowsupdate following error occurs:
import-module : Errors occurred while loading the format data file:
C:\Users\stackoverflow\Documents\WindowsPowerShell\Modules\pswindowsupdate\2.2.0.2\PSWindowsUpdate.Format.ps1xml, ,
C:\Users\stackoverflow\Documents\WindowsPowerShell\Modules\pswindowsupdate\2.2.0.2\PSWindowsUpdate.Format.ps1xml: The file was skipped because of the following validation exception: File

Use Get-ExecutionPolicy to set it e.g. to RemoteSigned:
Get-ExecutionPolicy -List
Set-ExecutionPolicy RemoteSigned
