Vista - How do I operate on (default) property of Registry provider?

1) Registry keys have so called default properties (with no name?). How do I
operate on them? For example how do I remove them?

Let's

0> Get-ItemProperty aa
....
p1 :
(default) :

(i.e. we have 2 properties including (default))

I tried:

0> Remove-ItemProperty aa '(default)'
… Property (default) does not exist at path HKEY_CURRENT_USER\a1\aa.

0> Remove-ItemProperty aa ''
… Cannot bind argument to parameter 'Name' because it is an empty string.

But Set-ItemProperty works with '(default)':

0> Set-ItemProperty aa '(default)' $null
0> Set-ItemProperty aa '(default)' 123
0> Set-ItemProperty aa '(default)' ''


2) Then, more fun: if I add a value with name '(default)' manually using
Regedit then I can't get properties at all:

0> Get-ItemProperty aa
… The member "(default)" is already present.

Is it a bug or what?

Perhaps, to avoid misunderstanding, I have to add that new keys have no such
(default) properties. Moreover, I can remove them manually by Regedit. But I
cannot remove them by PowerShell (or don't know how). And the same problems
are with copying them and etc.

Definitely looks like a bug. Please file it on http://connect.microsoft.com/.

Sorry for the inconvenience and thanks for letting us know.
