Windows 10 – Can’t deploy printers – Spooler error 0x000006BA / 0x000003EB

Hi everyone

Today I wanted to talk a small bug I seen from some Windows 10 with UWF enabled.

The error I seen was 0x000003EB and 0x000006BA


The error is pretty generic, but the system greyed all the printers in the Windows 10’s list, and you can’t connect to other printers from the server, nor add them by GPP or by deploying them.


In the past I used to use a Microsoft KB .exe to fix and erase all the spooler, by a hard reset, but the utility was removed from the website, as such to find the exact cause or to reset the error I suggest to get that small Kyocera’s utility (KM Deleter) now;


The error in my case seemed to come from UWF, as I unlocked the spooler folder for read and write, but I miss some registry key. As seen there;


As you can see no file or driver were present, but the registry were, so it blocked the Windows 10 to reconnect to those printers.

In my case I allowed more exceptions in the UWF, but you can see those two errors can happen if the driver is badly setupped, or missing necessary files.

Windows 10 IoT Terminal Deployment – Part 3.1 – Apps Publishing (HPDM – HP Device Manager)

Hi everyone

In the previous article series about deploying Windows 10 IoT terminal I talked about the global use in the Introduction, and secondly how to protect the C drive for unwanted change.

Now in this article I will bring subject, how to publish application to those terminals and I will start by talking HPDM.

It exist some way that we need to think about;

– Application pushed by a remote server and using the remote server ressources; Remote App, XenApp (technically speaking you need the RDSCAL to run XenApp, as such I tell about it there, but overall you must see XenApp as a feature set over RemoteApp)

– Applications pushed by a remote server, but running on the terminal; App-V, MSIX, XenApp Streaming Client (depreciated)

– Applications pushed by GPO (.MSI)

– Application pushed by HP Device Manager (HPDM)

Now the fact that we protect the hard disk bring us some limitations, as such in my guide I suggest for Office, or such application to be pushed by RemoteApp (or XenApp). The limitation is not only the fact the hard disk is using a UWF, but by the fact on IoT terminal the SSD is often small, and we try to not overuse it by product update. With a central server you can update the program and each terminal  would be using the latest version of the productivity’s suite.

I would start by talking of the HP Device Manager. On other articles I will cover other’s way.

We need to install it first and I suggest the latest version 5. We now need to have an account, and you need to ask to download, after we can got it free.


I will skip the install step as I want to focus on how to push the application correctly with the tool.

For the test I will push Google Chrome Enterprise.

At first we go inside the template menu in HPDM, and we want to push the file to the terminals;


We select the _File and Registry Template


Inside the template we click Add (Ajouter)


We click Deploy Files (Deployer les fichiers)


We click to add the Chrome Enterprise .msi




For the folder we select C:\TEMP, which is a special folder for the terminal.


We create an install.cmd (with that content), and we will push that file too;



Now we click Ok, HPDM will upload the file to its HTTP repertory and we click Generate.


After that we create a script action;



We save that, and now we do another template, a Sequence Template.


Inside the sequence, we need that;

  • We turn OFF HPWF or UWF.
  • Change Temp to C.
  • We deploy our first sequence’s files.
  • We change back Temp to Z.
  • We turn ON HPWF or UWF.

The task should look that way:


And voila, we can now deploy to any number of terminals we want the needed local application they need ! That finish that article.

Take care, and see you soon in the next article for that serie 🙂


Windows 10 IoT Terminal Deployment – Part 2 – Protect the Hard Disk ? – Deploy Write Filter !

Hi everyone !

In the second part of my article on how to deploy some thin client that run Windows 10 IoT I will talk on the write filter.

It exist three way to manage it that I know that exist;

1 – HP Write Filter (Shipping inside that terminal model as it’s a HP’s brand)

2 – Microsoft Unified Write Filter. That is new a new feature that come from EWF. (Shipped inside the terminal, as the Windows IoT is an Enterprise’s build)

3 – DeepFreeze (not free)

Today I will talk about HPWF and how to deploy the settings to the terminals.

To make the initial configuration to deploy, you must login inside one terminal to configure the overlay exception. We will capture the change after to deploy that.

We right click the HPWF management icon in the systray; it’s the green lock.


A side note; The green icon mean the overlay usage is ok, if it turn yellow or red, it mean it’s now in a critical state. To explain it, the overlay is stored inside the RAM, and each file change is stored inside of that buffer, it’s how the system can revert back the change after a reboot.


Let’s go back to our settings, when we will click the icon we will see which write filter is used;


Inside that windows we can click the More Settings to see which exception is set, and what use the overlay;


I put in red some exception that I did, as some default’s exception exist. The exception I really suggest to enable is for;

  • Your Antivirus product.
    • In that case I added TrendMicro and Windows Defender
  • The user profile if you intend to not use roaming profile, and that you want permanent settings for the user.
  • Chrome there, as the default behaviour of Chrome is to auto-update (which is not bad if you want to be secure in the long term)
  • I suggest too the Windows LogFiles folder.

The exception will allows our Antivirus to update in a day to day routine, while most of the program files and system folder will revert back.

I suggest to target a test user and test the terminal to see if the overlay cache stay in a consistent state. The goal is if the user write a lot of data to the hard-drive for a reason X, we need to know why.

With the why, we can try to push an needed application to a RDS server in example to prevent HDD usage, or if really needed we can make new exception.

Now to push the settings we need HPDM, which I talk more in detail in the part 3, but I will show you the task to do;

We need to capture the settings, and after we push the captured settings back to our terminals.

The two task w e need to know is:

 _Capture Write Filter Exclusion List

This template captures the FBWF/UWF exclusion list from a device running a Windows operating system with FBWF or UWF.

_Deploy Write Filter Exclusion List

This template deploys the write filter exclusion list to devices running a Windows operating system with FBWF or UWF


Thanks everyone for reading, stay tuned for the part 3 soon !


Windows 10 IoT Terminal Deployment – Part 1 – Introduction


Office 2019 / 365 Deployment

Hi everyone

Today I wanted to share some tips to deploy Microsoft Office 2019 to multiple computers.

The new way to deploy it differ from the older version as you now need to modify an XML file with the setup.exe

In the past we could do a customized setup by running the setup wizard, setup.exe /admin, which was creating a custom file for the setup. Now it’s all XML’s based.

First, you might need that setup if you use internally a KMS’s server:

Microsoft Office 2019 Volume License Pack 

This download is needed for administrators to set up activation for volume license editions of Office 2019, Project 2019, or Visio 2019 by using either the Key Management Service (KMS) or Active Directory.

After that download we will go find the deployment tool:

Office Deployment Tool

The Office Deployment Tool (ODT) is a command-line tool that you can use to download and deploy Office 365 ProPlus to your client computers. The ODT gives you more control over an Office installation: you can define which products and languages are installed, how those products should be updated, and whether or not to display the install experience to your users.

We now have everything we need, from there after we need to edit the XML file to add the option we need.

An example XML;

<Add SourcePath=”\\Server\Share”
Channel=”Broad” >
<Product ID=”O365ProPlusRetail”>
<Language ID=”en-us” />
<Language ID=”ja-jp” />
<Product ID=”VisioProRetail”>
<Language ID=”en-us” />
<Language ID=”ja-jp” />
<Updates Enabled=”TRUE”
UpdatePath=”\\Server\Share” />
<Display Level=”None” AcceptEULA=”TRUE” />
<Logging Level=”Standard” Path=”%temp%” />

We can see all XML options there, Configuration options for the Office Deployment Tool. As stated inside that article, and I confirm it too, it’s way easier now to use online tool on (


Now with a XML ready, we are now ready to issue a first command with the deployment tool;

setup.exe /download configuration.xml

The command will download the specific files needed to do the deployment. I suggest to copy those files to a central store to deploy to multiple machines.

Now we run that command to actually install the product;

setup.exe /configure configuration.xml



Now we are ready to use Office ! 😀


Windows 10 IoT Terminal Deployment – Part 1 – Introduction

Hi everyone

Today I will cover a topic that will fall into multiple subject and that not many blogger talk about; How to plan and deploy a lot of Windows 10 IoT terminals

In my test I used the new HP ThinClient (t430) that is bundle that way;

Operating system

  • Windows 10 IoT Enterprise for Thin Clients


  • Intel® Celeron® N4000 with Intel® UHD Graphics 600 (1.1 GHz base frequency, up to 2.4 GHz burst frequency, 2 MB cache, 2 cores)


  • Integrated: Intel® UHD Graphics 600


  • 4 GB DDR4-1866 SDRAM (1 x 4 GB)

Hard drive

  • 32 GB Flash memory

Network interface

  • Intel® Dual Band Wireless-AC 9260 802.11ac (2×2) Wi-Fi® and Bluetooth® 4.2 Combo

The look is that way; as you can see it’s really small and built to be flexible where to install, like able to fix them to the back of the monitor if needed.

It’s a handy device for place like a public library


These thin client advantage is that they come shipped with some management software and come with the full Windows 10 feature set. The Windows IoT for that model is an Windows 10 Enterprise LTSB build 1609.

Pre deployment, you have some questions to ask yourself;

– To protect the system drive; do you plan to use HP Write Filter (HPWF)  or Microsoft Unified Write Manager (UWF) out of the box ? or to use another product (like DeepFreeze)

– Where the user profile would be stored ? Roaming profile, Mandatory profile, Redirected folder, etc…

– As by default the system drive is locked (HPWF or UWF), do you plan to write exception for the user profile if it’s not a roaming profile ?

– How you will plan to deploy software, HP Device Manager, or with GPO ?

– As the device ram can be limited, and the system drive locked, do you plan to deploy a RDS server to deploy additional applications to the users ?

Some limitation you need to know before the deployment;

– The HPWF or UWF by default use a part of the RAM to store the files activities, which can limit what you use on the terminal.

– If you use a locked drive, you need to think for antivirus update, where you store them, so the machine could store the data (Write filter exception or thawed space)

– Windows Update need to be planned as by default the terminal does not update itself. So you must do sequential task usually to allow the Windows update install to stay inside the machine.

As you can see, to deploy such solution bring some questions, but in the end to think it before a deployment is the best course of actions, as it will lead to good user feedback in the end.

Thanks, and stay tuned for other articles coming soon !

I will talk next on how to deploy the machine + autojoin to the domain (part 3), how to manage and control the write filters with example (part 2) 🙂

Microsoft Team support for CentOS 7 / RedHat

Hi everyone

Today I just wanted to share a small tip.

If you want to support Microsoft Team inside CentOS 7 or RedHat you can now have a insider build, which could make it run.


Without it you could have error like that;

rpm -i teams-
warning: teams- Header V4 RSA/SHA256 Signature, key ID be1229cf: NOKEY
error: Failed dependencies: is needed by teams- is needed by teams- is needed by teams-

or that one too;

rpm -i teams-insiders-
warning: teams-insiders- Header V4 RSA/SHA256 Signature, key ID be1229cf: NOKEY
error: Failed dependencies: is needed by teams-insiders- is needed by teams-insiders- is needed by teams-insiders-


Thanks everyone

Prevent Office from saving to OneDrive by default


Today I wanted to share a small tip on how to prevent Office from saving to OneDrive by default ! A handy tip if you install Office on a Terminal Server or to your computers.

I share that tip as some users seen some information that the OneDrive save as location would be impossible to change.

IT pros, on the other hand, won’t be able to alter this Office 365 default save behavior. A Microsoft spokesperson explained this point in a Monday e-mail in response to questions:

IT admins will not have control over the save dialog. That said, end users can change their default save location for Office programs. Office programs will save files in the default location, but the default working folder can be changed. To then save the copy in a different location, the end user can click a different folder in the folder list.

Following that information I tried to find where to find the setting to change that default location, and yes I found it !

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Common\General PreferCloudSaveLocations : REG_DWORD : 00000000 :Hexadecimal

or there, but the user can change that one;


Now with that small tip you can now change that behavior 🙂


Windows 10 – NFS Mapping Error – Network Error – 53 Type ‘NET HELPMSG 53’ for more information

Hi everyone

If you find yourself with such error when you try to map a network drive in NFS;

Network Error – 53

Type ‘NET HELPMSG 53’ for more information

Please know that some tips exist to diagnose the error.

1- Make sure the NFS client is installed on the Windows 10.

2 – Make sure to use that registry fix if the mapping is on a restricted port;


UseReservedPorts := 0 (or 1) – DWORD32

3 – Make sure to use that registry fix to match the mapping GID/UID;


AnonymousGid := XXXX (usually 1001)

AnonymousUid := XXXX (usually 1001)

4 – In the linux server, make sure the /etc/exports is setting the insecure option.

NFS server has an option of working in insecure mode (Allowing higher incoming port numbers). Windows NFS client often uses higher port numbers. You can enable this option by adding an option to the share
Example: /share *(insecure,rw) ¹


As you can see it’s generic tips and of course disabling each firewall can’t hurt to diagnose 🙂



Windows 10 – Set default file association by GPO (Default browser to Chrome in my example)

Hi everyone

Today I will share a tip if you need to set the default file association for a bunch of computers by Group Policy.

In my example I want to make Chrome the default browser.

Someone could tell me, why I didnt used the Chrome Group Policy extension to set it by default ? I answer, because the Windows does not take it, as the file association for .htm is not changed by the Chrome GPO extension.

The first thing to do;

Change the default browser to Chrome there;

2019-12-17 (1)

After the change we need to generate an XML’s file to know the association set;

dism /online /Export-DefaultAppAssociations:C:\apps.xml


The file content would look that way;

<?xml version=”1.0″ encoding=”UTF-8″?>
<Association Identifier=”.3gp2″ ProgId=”WMP11.AssocFile.3G2″ ApplicationName=”Windows Media Player” />
<Association Identifier=”.adt” ProgId=”WMP11.AssocFile.ADTS” ApplicationName=”Windows Media Player” />
<Association Identifier=”.adts” ProgId=”WMP11.AssocFile.ADTS” ApplicationName=”Windows Media Player” />
<Association Identifier=”.fdf” ProgId=”FoxitPhantomPDF.FDFDoc” ApplicationName=”Foxit PhantomPDF 7.0″ />
<Association Identifier=”.htm” ProgId=”ChromeHTML” ApplicationName=”Google Chrome” />
<Association Identifier=”.html” ProgId=”ChromeHTML” ApplicationName=”Google Chrome” />
<Association Identifier=”.MP2″ ProgId=”WMP11.AssocFile.MP3″ ApplicationName=”Windows Media Player” />
<Association Identifier=”.mpa” ProgId=”WMP11.AssocFile.MPEG” ApplicationName=”Windows Media Player” />
<Association Identifier=”.MPE” ProgId=”WMP11.AssocFile.MPEG” ApplicationName=”Windows Media Player” />
<Association Identifier=”.mpeg” ProgId=”WMP11.AssocFile.MPEG” ApplicationName=”Windows Media Player” />
<Association Identifier=”.mpg” ProgId=”WMP11.AssocFile.MPEG” ApplicationName=”Windows Media Player” />
<Association Identifier=”.mts” ProgId=”WMP11.AssocFile.M2TS” ApplicationName=”Windows Media Player” />
<Association Identifier=”.pdf” ProgId=”FoxitPhantomPDF.Document” ApplicationName=”Foxit PhantomPDF 7.0″ />
<Association Identifier=”.ppdf” ProgId=”FoxitPhantomPDF.PPDF” ApplicationName=”Foxit PhantomPDF 7.0″ />
<Association Identifier=”.TS” ProgId=”WMP11.AssocFile.TTS” ApplicationName=”Windows Media Player” />
<Association Identifier=”.TTS” ProgId=”WMP11.AssocFile.TTS” ApplicationName=”Windows Media Player” />
<Association Identifier=”.WPL” ProgId=”WMP11.AssocFile.WPL” ApplicationName=”Windows Media Player” />
<Association Identifier=”.xdp” ProgId=”FoxitPhantomPDF.XDPDoc” ApplicationName=”Foxit PhantomPDF 7.0″ />
<Association Identifier=”.xfdf” ProgId=”FoxitPhantomPDF.XFDFDoc” ApplicationName=”Foxit PhantomPDF 7.0″ />
<Association Identifier=”http” ProgId=”ChromeHTML” ApplicationName=”Google Chrome” />
<Association Identifier=”https” ProgId=”ChromeHTML” ApplicationName=”Google Chrome” />

After that we need to create our GPO;

It’s in Computer Configuration\Administrative Templates\Windows Components\File Explorer\Set a default associations configuration file setting


As you can see I put my file inside NETLOGON, as all computer usualy have access there.


After that your default file association should work good ! 🙂
