Edit Remote Registry Key PowerShell

Hello,

We previously saw how to read the registry remotely. We can use a very similar method to open a registry key with write access as I explain the comments.

The PowerShell code to use will be pretty similar as the read operation, but we will use an overload of RegistryKey.OpenSubKey:

This allow us to open a remote registry key and write to it:

Edit Remote Registry Key PowerShell – Before

$NewValue = '111'
$Type = [Microsoft.Win32.RegistryValueKind]::String

$ComputerName = 'DC2-Core'
$Hive = [Microsoft.Win32.RegistryHive]::LocalMachine
$KeyPath = 'SOFTWAREMicrosoftNotepadDefaultFonts'
$Name = 'iPointSize'
 
$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($Hive, $ComputerName)
$key = $reg.OpenSubKey($KeyPath, $true)

$key.SetValue($Name,$NewValue,$Type)

Edit Remote Registry Key PowerShell – After

And voilà, the remote registry key is modified. You can edit a few types of registry items like this, you just need to change the $Type:

You can also create new sub keys with the CreateSubKey method and its overload:
