$InputFile = Import-Csv "C:\Test\SQLInstance.csv"

foreach($Servers in $Inputfile)
{
Write-Host "ServerName:" $Servers.instance
Get-WmiObject win32_service  -ComputerName $Servers.instance  | Select Name, Startmode, State  | Where-Object `
{$_.name -like "*SQL*" -and $_.Startmode -match "Auto" -and $_.state -match "Stopped"} | FT -AutoSize
}
