If (select-string -path "c:\Windows\System32\drivers\etc\hosts" -pattern "String to look for") `
    {(Get-Content c:\Windows\System32\drivers\etc\hosts).replace('String to look for', 'String to replace with') | Set-Content c:\Windows\System32\drivers\etc\hosts}
    Else{"Nothing happened"}

-1 Small correction for the Set-Content command. If the searched string is not found the Set-Content command will blank (empty) the target file. You can first verify if the string you are looking for exist or not. If not it will not replace anything.
