It’s easy for PowerShell toolmakers to forget that new users may have questions about ExecutionPolicy and Repositories. If dbatools is the first module you’ve ever installed and used, this guide is intended to help you with all of your install/setup questions and concerns.
In order to emulate what your experience may be like, I spun up a fresh Windows 10 instance in Azure and went through all of the required steps which include addressing:
Setting the Execution Policy
Explicitly trusting Microsoft’s PowerShell Gallery repository
Explicitly trusting dbatools as a Publisher, before first use
If you’ve never installed dbatools before, Chrissy shows just how easy it can be.
