To update powershell 3.0 help,
run Powershell as admin, enter following:
and hit ENTER
you will get a pile of "VERBOSE" messages, you will get red WARNING messages.
You have done nothing wrong. PS 3.0 also has a few quirks.
PowerShell Help is updated frequently, after all, PS 3.0 is still new.
I recommend, if you are a frequent user of PS, that you run update-help daily until they finally catch up.
