Automate user homedirectory creation Powershell - windows

Question

I'm automating the process of creating LocalUsers on Windows systems. So far I used the Microsoft docs on New-LocalUser which has worked fine to create the account, this is my code so far:
function New-AdminUser {
param(
[Parameter(Position=0)]
[string] $UNameLocal,
[Parameter(Position=1)]
[string] $UDescription,
[Parameter(Position=2)]
[System.Security.SecureString] $Password
)
New-LocalUser -Name $UNameLocal -Description $UDescription -Password $Password -AccountNeverExpires -Confirm
Add-LocalGroupMember -Group "Administrators" -Member $UNameLocal
}
But this command does not actually generate the homedirectory in C:\Users\username.
I can create this by manually logging into the created user, but I want to automate this in Powershell. I couldn't find anything in the LocalAccounts module.
Is there any way to automate local account setup in Windows 10 using Powershell, without having to manually log in to a new account?

Answer 1

If you start a process (cmd /c) as the created user, it will create his profile. Add this to your function:
$Cred = New-Object System.Management.Automation.PSCredential ("$UNameLocal", $Password)
Start-Process "cmd.exe" -Credential $Cred -ArgumentList "/C" -LoadUserProfile

Here is the code:
param([Parameter(Mandatory=$true)][String]$samAccountName)
$fullPath = "\\srv2012r2\Users\{0}" -f $samAccountName
$driveLetter = "Z:"
$User = Get-ADUser -Identity $samAccountName
if($User -ne $Null) {
Set-ADUser $User -HomeDrive $driveLetter -HomeDirectory $fullPath -ea Stop
$homeShare = New-Item -path $fullPath -ItemType Directory -force -ea Stop
$acl = Get-Acl $homeShare
$FileSystemRights = [System.Security.AccessControl.FileSystemRights]"Modify"
$AccessControlType = [System.Security.AccessControl.AccessControlType]::Allow
$InheritanceFlags = [System.Security.AccessControl.InheritanceFlags]"ContainerInherit, ObjectInherit"
$PropagationFlags = [System.Security.AccessControl.PropagationFlags]"InheritOnly"
$AccessRule = New-Object System.Security.AccessControl.FileSystemAccessRule ($User.SID, $FileSystemRights, $InheritanceFlags, $PropagationFlags, $AccessControlType)
$acl.AddAccessRule($AccessRule)
Set-Acl -Path $homeShare -AclObject $acl -ea Stop
Write-Host ("HomeDirectory created at {0}" -f $fullPath)
}
