I'm working on a script that is focused on pulling registry key values for directories used by SQL Server installations. This is the easiest way I can see to get them without having to use SMO or SQLPS, since I'll be working with different flavors of SQL Server. Where I am stuck is more logic in how to best do it than anything else. Everything I need is under the registry hive HKLM:\SOFTWARE\Microsoft\Microsoft SQL Server.
When you install an instance of SQL Server a sub key is created for your instance. The name of that subkey depends on the installation you did, default or named, and how many instances the server has installed. I have gotten down this code in order to pull out what instances are on a server, so I can build the full registry key path to get to the values I need:
With multiple ways to do some things in PowerShell, is there a better way to handle the above code? My first though I had typing this question up was to put the instance names in a hashtable.**
Where I am stuck in the logic is how to handle the $fullpath key once I have it built and then iterate through the registry keys I need to check. Then when I check them how to store the path (if it has one) to pass into a function I have written that will do something with the path.**
The registry keys...I have about 15 or so keys that may or may not exist under the $fullpath to get. An example would be the DefaultData and DefaultLog keys. They only exist if someone went into the SQL Server instance properties and put the path in. If you enter the Get-ItemProperty for a key that does not exist or does not have a value, it just returns you back to a prompt with no output. So instead of trying to do Test-Path on each registry key I figured I could somehow in the logic just check for "-ne $null".
The registry keys:

Personally, I'd use LogParser to get this data from across my domain into a SQL table and work from there. This is for 2 reasons:
The basic query is
You could get more specific but I dont have all the values you want to locate.
Then you can query this with TSQL.
