Should an account be set up and used solely to install SQL Server? I'd like to follow best practices.
However, is it overkill to create a new service account (with minimal access and no special rights) and then use that account to install SQL Server?
Are there downsides if I do the installation under my administrator account?
Side note: I already have separate service accounts that will run SQL Server engine and SQL Server Agent service.
There is no need or benefit to installing under a dedicated account as long as you are following other account-based best practices.
