Sorry we do not do that here. We can answer questions about scripting but you must learn how to write a script on your own.

You can find pre-written scripts here: https://gallery.technet.microsoft.com/ScriptCenter/

You must be an admin on all servers or you must log in local (at the console) of all servers.
