Powershell New-Service With User Credentials
Solution 1:
It needs an object of type PSCredential. It can be created manually using the command Get-Credential.
There are other ways, but they are a bit tricky because the password needs to be passed in as a SecureString.
You can find how to programmatically build a PSCredential object here.
Sample code:
$username = "username"
$password = "password"
$securepassword = ConvertTo-SecureString $password -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ($username, $securepassword)
New-Service [...] -Credential $cred
