you can do it by stopping SQL service from SERVICES AND APPLICATIONS.
first create the database with same name, than after stopping sql service, just simply copy paste the MDF and LDF files from your backup.
This won’t always work, as the sizes will be different from the sizes of the files that are listed in the master database. Not to mention why would you stop the instance to do something which you don’t have to take an outage to complete?
