I add a default parameter for Install-Module to set Scope to CurrentUser wherever I use the command. I explicitly set the scope to CurrentUser when I use it in build scripts (CI tooling).

I believe the default install location should be CurrentUser. A system level change should only occur when explicitly requested.

Expected Behavior

Modules installed using Install-Module should be placed in CurrentUser scope unless I explicitly request AllUsers scope.

Current Behavior

Modules installed using Install-Module attempt to install into AllUsers scope, I must explicitly request the less broad scope.

Possible Solution

The current default for the Scope parameter should be changed to CurrentUser:
