This function uses WMI to get a local user account. It returns a `Win32_UserAccount` object. The username has to be less than 20 characters. We don't remember why anymore, but it's probaly a restriction of WMI. Or Windows. Or both. You can do this with `Get-WmiObject`, but when you try to get a `Win32_UserAccount`, PowerShell reaches out to your domain and gets all the users it finds, even if you filter by name. This is slow! This function stops WMI from talking to your domain, so it is faster. .LINK http://msdn.microsoft.com/en-us/library/windows/desktop/aa394507(v=vs.85).aspx .EXAMPLE Get-WmiLocalUserAccount -Username Administrator Gets the local Administrator account as a `Win32_UserAccount` WMI object. #> [CmdletBinding(SupportsShouldProcess=$true)] param( [Parameter(Mandatory=$true)] [ValidateLength(0,20)] [string] # The username of the local user to get. $Username ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState return Get-WmiObject Win32_UserAccount -Filter "Domain='$($env:ComputerName)' and Name='$Username'" } |
