Why powershell? Win10 has bash now or python that runs on all OS.
That is PowerShell. It's native in all flavors of Windows since Seven. PowerShell if very useful to sys admins. However, depending on your size company maintaining scripts becomes frowned upon. It also depends on what you're trying to do e.g. audit, compliance, asset mgmt, IDAM . . . etc. For large and I mean large 150K global users, they tend to use 3rd party off the shelf software. This is usually done for insurance, risk, (industry) security purposes.
Even after saying all of that, it's still good to now PowerShell.
