When you first try to run a PowerShell *.ps1 script on Windows, you will probably get the following error message:
File C:\Users\Mike\AppData\Roaming\npm\nest.ps1 cannot be loaded because running scripts is disabled on this system.
Why this error occurs
By default, all Windows versions - Windows 11, Windows 10, Windows 7, Windows Server,... - have the script execution disabled for security reasons.

PS D:\Projects\test> nest new nest-demo-1

system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.
