Set registry key owner

RichardSiddaway — Fri, 11 Nov 2011 06:00:00 GMT

In chapter 7 of PowerShell and WMI I stated that I would post a .NET version of a script to set ownership of a registry key. The WMI method needs Vista or above so we need the .NET version for pre-Vista operating systems.

function set-regkeyowner {            
[CmdletBinding()]            
param (            
 [parameter(Mandatory=$true)]            
 [string]            
 [Validateset(“HKCR”, “HKCU”, “HKLM”, "HKUS", "HKCC")]            
  $hive,            
            
 [parameter(Mandatory=$true)]            
 [string]$key            
)              
PROCESS {             
Write-Verbose "Set Hive"            
switch ($hive){            
 “HKCR” {$reg = [Microsoft.Win32.Registry]::ClassesRoot}            
 “HKCU” {$reg = [Microsoft.Win32.Registry]::CurrentUser}            
 “HKLM” {$reg = [Microsoft.Win32.Registry]::LocalMachine}            
 "HKUS" {$reg = [Microsoft.Win32.Registry]::Users}            
 "HKCC" {$reg = [Microsoft.Win32.Registry]::CurrentConfig}            
}            
            
$permchk = [Microsoft.Win32.RegistryKeyPermissionCheck]::ReadWriteSubTree            
$regrights = [System.Security.AccessControl.RegistryRights]::ChangePermissions            
            
Write-Verbose "Open Key and get access control"            
$regkey = $reg.OpenSubKey($key, $permchk, $regrights)            
$rs = $regkey.GetAccessControl()            
            
Write-Verbose "Create security principal"            
$user = New-Object -TypeName Security.Principal.NTaccount -ArgumentList "Administrators"            
            
$rs.SetGroup($user)             
$rs.SetOwner($user)             
$regkey.SetAccessControl($rs)            
}            
}

Take a hive and key as parameters. Use a switch to set the Registry enumeration and then set the permissions and rights we want. Open the key and get the access controls.

Create a security principal for the Administrators group and set the group and owner in the access control. Use SetAccessControl to change the permissions

unlock mystify, ribbons and bubbles screensaver settings [How To]

Anonymous — Tue, 01 Mar 2011 06:00:00 GMT

I’m guessing that the screen savers themselves doesn’t need any introduction. Many people like the Mystify, Ribbon or Bubbles screen saver, but secretly wish they could tweak them, ever so slightly. Having just one mystify ribbon scrolling over your screens – it seems lonely. Having a small monitor, the bubbles get too big. Word has [...]

Change the Categories arrangement in Control Panel [How To]

Anonymous — Sat, 29 Jan 2011 06:00:00 GMT

To make things easier (for the common user) Microsoft decided to Categorize the Control Panel view. I never could get used to the new categories view, thinking that some of the panel applets were in the wrong category. Instead, I always immediately switch back to the “Classic” Control Panel view. I recently learned that you [...]

Getting attacked by virus and Trojans in itself is an annoying experience. And if you’ve been so lucky as to get one of those intruders that delete or turn off Windows features… I feel your pain. Even when the virus or Trojan are removed, users are still facing the possibility of spending many hours going [...]

Enable the Hidden Administrator Account in Windows XP [How To]

Anonymous — Tue, 30 Nov 2010 06:00:00 GMT

I have written a guide for next week that explains running tasks as an administrator in Windows XP. Just like modern cars (some, not all) don’t fully turn off the traction control even when you press the switch, modern versions (including XP) don’t give you full administrative permissions (even with an Administrator account.) Thus, you’ll need to [...]

Previously, Angel Luis showed you how [...]
