What programs do administrators need?

Question

System administration

And what programs do you use to simplify the process of administration at work?
Just now I came across the fact that there is no domain at the new job, nothing in principle. And for mass operations (install a shortcut, antivirus, etc.), these operations have to be carried out manually. But introducing a domain is a little scary, because. still haven't had to administer it.

Answer 1

Implement a domain if there are more than 10 machines

Answer 2

Hyena and PDQDeploy. But they mean the presence of a domain - without it, all the functionality will not work.
