Registry 1

In this http://itknowledgeexchange.techtarget.com/powershell/wmi-and-the-registry/ and subsequent posts I looked at using WMI to work with the Registry.  As part of a series examining .NET classes that are useful to admins I thought it would be interesting to look at the Registry first.

We start by linking to a registry hive in this case HKLM – the local machine hive

$reg = [Microsoft.Win32.Registry]::LocalMachine

 

We can then access a subkey.

$key = $reg.OpenSubKey("Software\ITKE PSAdmins")

 

This is the example key I created in the WMI series so you need to read that to see how I created it.

We can get the number of values

$key.ValueCount
4

Their names

$key.GetValueNames()
String Entry
Expanded String Entry
Dword Entry
Multi-string Entry

 

and their types

$key.GetValueNames() | foreach {"$_   $($key.GetValueKind($_))"}

String Entry   String
Expanded String Entry   ExpandString
Dword Entry   DWord
Multi-string Entry   MultiString

 

and the actual values

$key.GetValueNames() | foreach {"$_   $($key.GetValue($_))"}
String Entry   This is a string
Expanded String Entry   C:\Users\Richard\AppData\Local\Temp
Dword Entry   101
Multi-string Entry   A B C D
