As you know, the registry has DWORD, string, expand string, multi string, binary, and Qword value types. Let us take one by one. In all the examples I provide below, I will create/modify values under the HKLM Software Techibee key for the sake of demonstration. Hi, I am trying to recurse through a remote registry key path and search through it for a value name and get the value data.Hence i need to give it atleast a subkey to start from so as to avoid searching time delay through many nodes. We will how to write a value in the registry of a remote PC enable remoting. The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands sent for differnet operations. Dismiss Join GitHub today.

FunctionGet-SqlServerKey{
<#
.SYNOPSIS
Gets SQL Server Product Keys from local on destination SQL Servers. Works with SQL Server 2005-2014
.DESCRIPTION
Using a string of servers, a text file, or Central Management Server to provide a list of servers, this script will go to each server and get the product key for all installed instances. Clustered instances are supported as well. Requires regular user access to the SQL instances, SMO installed locally, Remote Registry enabled and acessible by the account running the script.
Uses key decoder by Jakob Bindslet (http://goo.gl/1jiwcB)
.PARAMETER SqlServers
A comma separated list of servers. This can be the NetBIOS name, IP, or SQL instance name
.PARAMETER SqlCms
Compiles list of servers to inventory using all servers stored within a Central Management Server. Requires having SQL Management Studio installed.
.PARAMETER ServersFromFile
Uses a text file as input. The file must be formatted as such:
sqlserver1
sqlserver2
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
$cred = Get-Credential, this pass this $cred to the param.
Windows Authentication will be used if DestinationSqlCredential is not specified. To connect as a different Windows user, run PowerShell as that user.
