Here’s something I don’t do often enough to commit to memory, create your profile. If you have anything you want to run when you fire up powershell (sql server & sqlpsx modules, etc…) you need first to create your profile. You can do so with the following command:
New-Item -path $profile -type file -force
You can then edit your profile by typing in:
notepad $PROFILE
