Delete one local user account if another local adminstrator ID exist - powershell

Question

I have few numbers of server where "tempadmin" and "Administrator" are exist as local admin user. I need to delete "tempadmin" id if "Administrator" is also exist. else "tempadmin" needs to rename as "Administrator". Could anyone help me create one PowerShell script?
cls
$strComputer = Get-Content "c:\patch\clientlist.txt"
$password = Read-Host "Enter the password : " -AsSecureString
foreach ($server in $strComputer) {
Write-Host "Working on server $server"
if (Test-Connection $server -Quiet) {
$usertest1 = Get-WMIObject Win32_UserAccount -Filter "LocalAccount=True AND Name='test1'" -ComputerName $server
if ($usertest1.name -ne 'test1') {
$user = Get-WMIObject Win32_UserAccount -Filter "LocalAccount=True AND Name='test'" -ComputerName $server
$result = $user.Rename('test1')
if ($result.name -eq 'test') {
$result
# you may just print a message here
}
Write-host "$server -> ID renamed and resetting password...."
$user1 = Get-WMIObject Win32_UserAccount -Filter "LocalAccount=True AND Name='test1'" -ComputerName $server
([adsi]("WinNT://" + $server + "$user1")).SetPassword("$password")
Write-Host "$server -> Password reset successfully"
} else {
Write-Host "$server -> Test1 ID already exist"
}
} else {
Write-Host "$server -> server is not reachable"
}
}
Here I am user "test" and "test1". I tried the above code and I can successfully rename and reset the password. But I am unable to delete if both ID's are exist.

I would try something like this:
$VerbosePreference = 'Continue'
foreach ($C in $Computer) {
if (Test-Connection $C -Quiet) {
Write-Verbose "$C > Online"
$Users = Get-WMIObject Win32_UserAccount -Filter "LocalAccount=True" -ComputerName $C
if ($Users.Name -contains 'Administrator') {
Write-Verbose "User 'Administrator' found"
if ($Users.Name -contains 'tempadmin') {
Write-Verbose "Delete user 'tempadmin'"
$ADSI = [ADSI]"WinNT://$C"
$ADSI.Delete('User','tempadmin')
}
}
else {
Write-Verbose "User 'Administrator' not found"
# Here you can rename the 'tempadmin' account or create a new 'Administrator'
}
}
else {
Write-Verbose "$C > Offline"
}
}
It's not complete but I'm sure you get the idea here. It's always better to query a client once and then loop through the collection of objects instead of querying multiple times to check for different objects in each query.
I hope this helps you out or gives you some ideas.
