OpenRemoteBaseKey() credentials

Just thought I'd add my answer to anyone with this problem as well. It seems there is no way to add Credentials using RemoteRegistry. You can however use WMI to query a remote registry using alternative credentials as follows:

$reg = Get-WmiObject -List -Namespace root\default -ComputerName RemotePC -Credential "Domain\User" | Where-Object {$_.Name -eq "StdRegProv"}

From here you can call standard Registry methods. The below example will return the operating system.

$HKLM = 2147483650$reg.GetStringValue($HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion","ProductName").sValue

Hope this helps someone :)

Are you running remote registry service? It is disabled by default and that must be causing the issue. Check the status of this service on all remote machines you are trying to access.

I couldn't comment directly on bentaylr's entry above, but I've taken what he contributed and added PSCredentials creation (figured out from here) to allow you to hard code credentials into the script.

Peace of mind disclaimer: Be careful when using plaintext credentials in a script. In my case, I'm using generic credentials on machines I'm launching. Depending on your case, you might consider creating an encrypted credential file to store the password in (see link above).

The credentials you use would need to be able to access the registry if you were logged into that user on the machine you are targeting.

$user = "Domain\Username"$pass = ConvertTo-SecureString "Password" -AsPlainText -Force$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $user,$pass$reg = Get-WmiObject -List -Namespace root\default -ComputerName $server -Credential $cred | Where-Object {$_.Name -eq "StdRegProv"}$HKLM = 2147483650$value = $reg.GetStringValue($HKLM,"Software\Microsoft\.NetFramework","InstallRoot").sValue
