How do I use -Credential parameter?

[TonyDeSweet]

There are some buildin cmdlets with -Credential parameter (for example
those *-Item cmdlet). But when I used those cmdlet with -Credential, I
always got an error (no matter it is Filesystem provider or registry
provider).

Is there something I did wrong or Is it designed to act like that?

=======================================================
C:\WINDOWS> new-item . -Name my.txt -type "file"

FileSystem and Registry provider do not supprt Credential parameter for V1.
We plan to address this in V2. For now you will need to start an elevated
MSH window using runas.exe (or Process.Start api) and carry out the required
operations there.
