RES Automation Manager Quick Tip – appending to existing registry values

I was recently asked (by one of our existing RES Automation Manager customers) how they go about adding to an existing registry value using RES Automation Manager. Well the answer is simple really – by using the @REGISTRY function. I’ll detail how you go about using this function in this blog post.

Firstly start the RES Automation Manager console;
Select “Modules” from the left hand pane, Right Click and select “Add”;
Give the module a suitable name then select the “Tasks” Tab, Right Click and select “Add”.
Select the task “Registry Setting (Apply,Query)” and select “Apply”.
You will now be presented with a dialogue where you can select various methods to add the required registry value you wish to append too. In my example I’m going to APPEND a new string to the START of the existing USERINIT registry value. Select “HKEY_LOCAL_MACHINE” from the left hand pane, Right Click and select “Open HKEY_LOCAL_MACHINE…”.
Browse to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon” and select “Userinit”, this will add this value to the current dialog box.
Now we are going to add the @REGISTRY function to the Userinit value by Right Clicking on “Userinit” in the right hand pane and selecting “Modify”.
In the “Value Data” field, Right Click and select “Insert Functions” >; “@[REGISTRY(;)]”.
RES Automation Manager now provides you with a nice GUI that allows you to browse to the registry value you wish to retrieve, when the job is executed on the agent. In my case this is going to be the registry value I selected in Step 6, as this is the value I’d like to append too.
Now I simply add the new value that I wish to append, before the @REGISTRY function or after, depending where I’d like my value to appear – in my case this value is “MyNewValuetoAppend” [code]MyNewValuetoAppend,@[REGISTRY(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon)][/code]
The resulted registry value now looks like this, once the job has been scheduled and completed [code]MyNewValuetoAppend,C:\Windows\system32\userinit.exe[/code]

That’s all there is to it! Smile

Move Machine Based Context Menus to Per User (Part I)

WARNING! This post requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Virtual Engine cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you begin. If this hasn’t scared you off keep reading….

In my time installing and configuring applications for multi user environments like XenApp or RDS, I come across many applications that will create context menus within Windows explorer that can help a user quickly perform a function. The screen shot below shows how WINRAR has added context menus in Windows explorer that allows the user to easily create a .RAR file having selected file(s) or folder(s).

Generally these context menus are machine based, i.e. any user that logs in to a XenApp server will be able to see and use these context menus. On the face of things you might ask yourself why would this be a problem? Well suppose this application is strictly licensed for particular/named users. Therefore, you wouldn’t want anyone having the option to use them otherwise you would need to license the application for all users! In this case what you’d really like is to only have them available to users whom are licensed or whom you deem need them. A typical example of this might be Adobe Acrobat Professional that adds in a context menu to combine documents to single PDF.

The good news is there is a way of moving them from being machine based to per user with some fancy manipulation of various registry keys. So lets begin using our example of WINRAR and see how this can be done.

Firstly, we need to understand where context menus are located within the registry. From my experience when you right click on file(s) within windows explorer the context menus will be found in:

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

Here’s an example with WinRAR:

When you right click on folder(s) within windows explorer the context menus will be found in one or both of the following registry locations:

HKEY_CLASSES_ROOT\Folder\ShellEx\ContextMenuHandlers
HKEY_CLASSES_ROOT\Directory\ShellEx\ContextMenuHandlers

Below is a screen shot showing these registry keys for WinRAR:

So now we know where they are located we should open up the registry editor (REGEDIT.EXE) and export the context menu registry keys that we would like to make per user to .REG files (saving them to a location for safe keepings should you need to revert it back!).

What we need to do next is take a copy of those same registry (.REG) files so we can edit them. Using those copies open them in say notepad and replace HKEY_CLASSES_ROOT with HKEY_CURRENT_USER\Software\Classes (this is where the equivalent registry keys are kept for a user). It should now look something like this; using WinRAR as the example. Once completed save and close the .REG file.

Now we get dangerous (well not really if you’re in the registry all time adding, deleting and generally tinkering – sound familiar?!?). The next step requires us to alter the permissions of those context menu registry keys located in:

HKEY_CLASSES_ROOT\Folder\ShellEx\ContextMenuHandlers
HKEY_CLASSES_ROOT\Directory\ShellEx\ContextMenuHandlers
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers

Again using WINRAR as the example I would open up REGEDIT.EXE and browse to the following locations:

HKEY_CLASSES_ROOT\Folder\ShellEx\ContextMenuHandlers\WinRAR
HKEY_CLASSES_ROOT\Directory\ShellEx\ContextMenuHandlers\WinRAR
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\WinRAR

Modify the ‘Users’ permissions from ‘Read’ to ‘Deny’ on each registry key (as listed above) like so:

Having changed those permissions you have successfully removed the context menus from a per machine basis or more precisely denied access to users and administrators. I’m no fan of doing things manually so I try and automate where possible. My choice of tool to change the registry key permissions in that automated fashion would be to use RES Automation Manager which has a built-in task to manage registry key functions, e.g. registry permissions. Unfortunately there appears to be a bug – which has been logged with RES Support – in RES Automation Manager for this task when the registry key contains “*” i.e.

HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\WinRAR

So I turned to the ever reliable SetACL from Helge Klein (follow Helge on Twitter here) to set the required registry permissions and added the command line into my RES Automation Manager job. For any existing users of RES Automation Manager I’ve attached a handy building block (just click on the big red brick) that can be used and manipulated for your needs to change those permissions as described above.

In Part II of this blog post I’ll describe how you go about targeting these same context menus at specific users .

Enjoy!

Locating Computer GPO Registry Values

I come across this scenario all the time that requires a HKLM registry setting to be configured. Typically this can be implemented via Group Policy but, for whatever reason, you which to set the resulting registry value directly. It might be because you don’t wish to cut a new GPO just for a couple of servers or workstations. A common requirement is to set the RDS licensing server as part of an automated deployment. Maybe you use RES Automation Manager like we do. However, this scenario is not limited to just RES Automation Manager. You could use the information in this post to configure a few specific settings as part of a WDS deployment for example.

Hopefully by now you are all familiar with the free Virtual Engine Toolkit (VET). No!? Shame on you! I suggest you take a look over here and see how it can help migrate from a unmanaged user environment to a managed one.

So you now know VET is especially good at converting user related GPOs into .REG files that can be imported in your UV/UEM tool of choice i.e. RES Workspace Manager or AppSense Environment Manager. One of VET’s hidden talents (and undocumented until now) is we can also convert computer related GPO’s into .REG files.

Using the settings above as an example I’ll run you through how we achieve this with RES Automation Manager and not in a GPO. If you’ve read our series on user GPO migration then you’re aware that GPO settings (not all!) are just registry settings. The problem we normally have, is where and what should these values be set to?

You could at this point download the Microsoft Group Policy Settings Reference guide and find the individual registry keys. You could use the Group Policy Search which Kees Baggerman spotted and pointed out in this blog post Winking smile . You can spend time Googling them at which point you would have to start manually adding them to the registry task in AM. But its much, much simpler to use VET!

NOTE: the same process could be used for migrating multiple existing computer related GPOs into AM but please be aware that the computer will probably need a reboot before the targeted settings come into force.

First thing to we need to do is create a Dummy GPO where we can set the various policies we’d like included in AM. In my example I’ve called my GPO “Dummy GPO for VET” and configured the settings we’d like to apply as in our example above.
Next we need to launch VET and use the “Convert Group Policy Objects Wizard” to scan the SYSVOL folder for our newly created/existing GPO. Once VET displays the list of GPOs select the one that you wish to convert then click “Next”
.
Select “Use subfolders for User and Machine policies”. Deselect “Also create RES Workspace Manager Building Block Files” then click “Next”, “Next” and “Finish”.
Looking in the “Documents\Machine” folder you’ll find the newly created .REG File containing our settings.
Now launch the RES AM console and create a new module which contains the “Registry Settings (Apply)” task. Its then a case of importing the .REG File created previously; so you should end up with something looking like this.

It’s as simple as that! We’ve used a dummy GPO that is not applied to any computer objects, set our required settings and imported the exact resultant registry values into RES Automation Manager. You can probably think of other great use cases for this too.

You never know we might incorporate the ability for VET to generate RES Automation Manager building blocks in the future.. Hope this little gem helps someone in the future like it has me!

Active Setup – Stubpath Command Lines

I spend a lot time working with mandatory profiles and RES Workspace Manager, especially when using Citrix XenApp or Remote Desktop Services. One of the key elements to creating a slick mandatory profile is to ensure the Active Setup keys are added to the mandatory profile or you will forever see the annoying “Personaliz(s)ing Settings” message. We have covered how to do this in a previous post here by using our great free tool the Virtual Engine Profile Update Utility (PuU).

While you can merge these Active Setup Keys to stop the message box appearing; this isn’t actually where the story ends. Behind some Active Setup Components there is a command line (Stubpath) that needs to run once per user i.e. for new users logging on for the first time (for a great explanation of Active Setup, check out Helge Klein’s write up here). The drawback of just merging these keys will be that the command line (Stubpath) will not run for any user. This could have undesirable results as mentioned in the RES Blog post here and Andrew Morgan’s Blog post here.

So the purpose of this blog is really for informational purposes above anything else and to detail the most common Active Setup components containing Stubpaths, by OS. Should you need this information, it’s here for reference. For example, if you disable the ActiveSetup option within RES Workspace Manager or merge the ActiveSetup keys using the Profile Update Utility (PuU), you may have to reinstate a particular action if it causes issues (like Andy’s issue). The command line (Stubpath) is highlighted in yellow and can be used to remedy the situation if necessary:

UPDATE : Windows 8 Consumer Preview (Subject to Change) – Yes ActiveSetup is still here!

RES Workspace Manager Registry Import Bug

[UPDATE 01/08/2011 – RES have released a fixpack for RES Workspace Manager 2011 SR1 that resolves the issues highlighted in this post. I don’t have any word on whether this fix will be rolled into the next Service Release of RES PowerFuse 2010 (SR5?). I hope so as we can then remove this post. In the meantime, please contact RES Software support to obtain this fix (assuming you’re running WM 2011 SR1!)]

An issue has been discovered in RES Workspace Manager 2011 and earlier versions (e.g. PowerFuse) when importing .REG files. Ironically, this was discovered when converting existing Group Policy Objects via the Virtual Engine Toolkit (VET). RES Workspace Manager does not implement the removal/deletion of registry keys or values correctly. It has been reported to RES Software and they have acknowledged there is an issue. It is not an issue with the Virtual Engine Toolkit but a problem with any .REG file, i.e. one’s migrated from log on scripts etc. [UPDATE – for clarification purposes, a support ticket had been raised prior to this post and RES are working on a fix.]

The following snippet from a REG file (some entries removed for clarity) should toggle the removal of NoInternetIcon and NoNetHood values and also toggle the removal of the \Software\Policies\Microsoft\Windows\NetCache\AssignedOfflineFolders key.

Windows Registry Editor Version 5.00;
Created by the Virtual Engine Toolkit v0.9.7.0;
Creation date: 05-30-2011 17:04:08

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
“DisablePersonalDirChange”=dword:00000001
“NoDesktopCleanupWizard”=dword:00000001
“NoInternetIcon”=-
“NoNetHood”=-

-[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\NetCache\AssignedOfflineFolders]

What actually happens is RES Workspace Manager sets the two DWORD vales to 1 and doesn’t even import the \Software\Policies\Microsoft\Windows\NetCache\AssignedOfflineFolders key as shown below. This results in complete unexpected behaviour and might impact any Proof of Concept or pilot deployments.

Hopefully this issue will get resolved promptly but in the meantime, please be vigil!
