Retrieving registry values with Get-ItemProperty

Regarding registry queries, I've often seen the advice that you need to specify the name of the property with get-itemproperty, and then use the property name again using the dot method to retrieve the value. For example:

(Get-ItemProperty HKLM:\SOFTWARE\Intel\Infinst -name Infver).Infver

Open in new window

However, in my experience there's no need to supply the name twice. The below works just fine.

(Get-ItemProperty HKLM:\SOFTWARE\Intel\Infinst).Infver

Open in new window

I was wondering if anyone knew some background on this and whether there are any circumstances where my method wouldn't work. It's been tested with both PS 2.0 and 3.0, don't know about 1.0. I can't understand why the previous advice prevails when it doesn't seem to be needed.

Interesting observation. The syntax does seem to behave more like the -filter parameter on gci than the -include parameter (for instance, using wildcards). If I ever run into a reg key with a large amount of values, I'll have to remember this and see if there's any measureable performance difference.

If we could use get-itemproperty remotely, the potential impact would be noticable - if there is any.
