Notice that the output here is quite a bit different than what you would see from a regular file system

drive. That is because the information held in the Registry is so much different than files and directories.

The Registry is made up of keys, which can be thought of as containers. Keys can contain sub - keys and

property values that are properties of the key in which they are contained. Sub - keys can contain more

sub - keys and property values of their own.

In the output from

dir in the previous example, the objects listed under the Name column are sub - keys

in the

MSExchangeIS key. The SKC (sub - key count) column denotes the number of sub - keys contained in

that sub - key. The

VC (value count) column contains a count of the number of values in that sub - key. The

Property column lists each property value. For example, the Diagnostics sub - key contains three

sub - keys of its own, but no property values. The

Performance sub - key contains no sub - keys, but has

13 property values.

To work with Registry keys, use

Item cmdlets: Get-Item , Set-Item , Rename-Item , Copy-Item ,

Move-Item , and Remove-Item . To work with Registry property values use ItemProperty cmdlets:

Get-ItemProperty , Set-ItemProperty , Rename-ItemProperty , Copy-ItemProperty ,

Move-ItemProperty , and Remove-ItemProperty ...
