function Get-DbaRegistryRoot { <# .SYNOPSIS Uses SQL WMI to find the Registry Root of each SQL Server instance on a computer .DESCRIPTION Uses SQL WMI to find the Registry Root of each SQL Server instance on a computer .PARAMETER ComputerName The target computer. This is not a SQL Server service, though if you pass a named SQL instance, it'll parse properly down to the computer name .PARAMETER Credential Allows you to login to $ComputerName using alternative Windows credentials .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Server, Management, Registry Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Get-DbaRegistryRoot Gets the registry root for all instances on localhost .EXAMPLE PS C:\> Get-DbaRegistryRoot -ComputerName server1 Gets the registry root for all instances on server1 #> [CmdletBinding()] param ( [parameter(ValueFromPipeline)] [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [switch]$EnableException ) process { foreach ($computer in $computername) { try { $sqlwmis = Invoke-ManagedComputerCommand -ComputerName $computer.ComputerName -ScriptBlock { $wmi.Services } -Credential $Credential -ErrorAction Stop | Where-Object DisplayName -match "SQL Server \(" } catch { Stop-Function -Message $_ -Target $sqlwmi -Continue } foreach ($sqlwmi in $sqlwmis) { $regroot = ($sqlwmi.AdvancedProperties | Where-Object Name -eq REGROOT).Value $vsname = ($sqlwmi.AdvancedProperties | Where-Object Name -eq VSNAME).Value $instancename = $sqlwmi.DisplayName.Replace('SQL Server (', '').Replace(')', '') # Don't clown, I don't know regex :( if ([System.String]::IsNullOrEmpty($regroot)) { $regroot = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'REGROOT' } $vsname = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'VSNAME' } if (![System.String]::IsNullOrEmpty($regroot)) { $regroot = ($regroot -Split 'Value\=')[1] $vsname = ($vsname -Split 'Value\=')[1] } else { Write-Message -Level Warning -Message "Can't find instance $vsname on $env:COMPUTERNAME" return } } # vsname takes care of clusters if ([System.String]::IsNullOrEmpty($vsname)) { $vsname = $computer if ($instancename -ne "MSSQLSERVER") { $vsname = "$($computer.ComputerName)\$instancename" } } Write-Message -Level Verbose -Message "Regroot: $regroot" Write-Message -Level Verbose -Message "InstanceName: $instancename" Write-Message -Level Verbose -Message "VSNAME: $vsname" [PSCustomObject]@{ ComputerName = $computer.ComputerName InstanceName = $instancename SqlInstance = $vsname Hive = "HKLM" Path = $regroot RegistryRoot = "HKLM:\$regroot" } } } } } |
