Windows Licence Types

During a computer rebuild, I needed to determine if my copy of Windows 10 Pro would remain activated after some serious hardware modifications. During the process, I learned there are three main types of Windows licences and that they are generally bound to the motherboard in use. Therefore, if you change the motherboard of the computer, Windows will need to be reactivated. Whether or not it will reactivate without a fuss depends on which of the three licences you are using.


You likely get a retail version of Windows when purchase it as a stand alone product either from either a shop or the Microsoft store. Retail Windows licences can be transferred between computers, as long as the licence is only in use by one computer at a time. Therefore, you can make as many hardware modifications as you like and Windows will still activate successfully.


OEM Windows licences are generally supplied with computers from the manufacturers, however it is possible for someone to purchase the licence from a shop. If purchased separately they are usually available for a reduced cost. These licences can only be used on the computer they were originally activated on, therefore replacing the motherboard on one of these systems will cause Windows to deactivate and refuse to reactivate.

Another interesting point arises for the OEM licence if you were to purchase one from a reseller. The person or company who purchases the licence takes responsibility for providing support for the activation process. Therefore, if you buy one of these licences and have problems with activation, Microsoft are likely to tell you to contact the OEM (which is you) for assistance. Alternatively, with the full retail version, Microsoft will provide support for any problems encountered with activation.


These licences will not impact your average home user, as they are provided to organisations to use on the computers they own. The cannot be re-sold and if the computer changes ownership, the licence technically needs to be removed.

Determine Your Licence Type

Like me, many of you likely do not know what kind of Windows licence you possess. Luckily, there is an easy command which can be run from the Window’s command prompt, or PowerShell, which will show you. Just enter slmgr -dli and a dialogue box will open showing you the licence type.


Alienware Laptop VPN Issues

My Alienware laptop seemed unable to connect to any VPNs using the Windows inbuilt VPN feature. I had tested the exact same VPN on another computer and it worked correctly.

I ran through a number of different troubleshooting methods found on the Internet, including trying a number of different authentication settings suggested. However, none of these methods were successful.

As all of these methods appeared to solve most of the problems other people were having, I started to think the problem was more specific to my system. To test this theory I removed some of the additional networking features on my system including:

  • Uninstalling the OpenVPN TAP adapter
  • Disabling Hyper-V on the system to remove the additional network adapters it added

However, neither of these methods solved the problem. Finally, I uninstalled the “Killer” network drivers and software installed on the laptop from the factory to support the Killer WiFi and Ethernet cards installed in the laptop. After uninstalling the software, the VPN was suddenly able to connect. I have no idea why this software was causing the VPN to fail, however uninstalling it fixed the problem and does not seem to have impacted the performance of my networking hardware.

Audio Books for the Vision Impaired

My Great Aunt has always been an avid reader of books. However, with the onset of Macular Degeneration, her sight has degraded to the point where she can no longer read. Once this occurred, I began searching for a way to continue reading the books she wanted without her sight.

A Flawed Solution

An immediate solution that came to mind was to get her audio versions of the books she wants to read. A family friend made me aware of a organisation known as Vision Australia that supplied small audio players which could be used to listen to audio books. These players made use of a 3G cellular connection to connect to a library of audio books where they can pick a book and listen to it on demand. This seemed like a brilliant idea, however the implementation turned out to be flawed.

Firstly, The Player…

The device itself appears to have been adapted from an old CD player of some kind and unfortunately the buttons had not been modified in any way. This in my opinion made it unnecessarily hard to operate. I won’t go into too much detail, however the basics are that myself, with a Bachelor degree in IT and perfect vision, took an amazing amount of time working out how to use it. I then had great difficulty showing my Great Aunt how to operate it, compounded by the fact that there were no clear markings on the buttons which she could feel.

Now, The Library

An additional problem stems from the amount of time they allow you to lease a book from the library for. Many of the audio books my Aunt was interested in listening to lasted for more that 20 hours. However, the leases on them were only available for one or two weeks, and in many cases a shorter time frame than that. Even listening for two hours a day didn’t allow her to complete many of the books. At the end of the lease period, the book was simply deleted, leaving her unable to finish them.

A Solution that Works

I’m not claiming that this solution is perfect or will work for everyone, however it does allow my Great Aunt to start and stop listing to a book independently. I created her account, which is an audio book platform owned by Amazon and has an extensive number of books available. I then installed the Audible app on an old iPad I had laying around. I also found a pair of headphones which have the play/pause button located on the wire going up to one of the ear pieces.

I purchase the book she wishes to listen to and using the app download it to her iPad and start it playing. She can now pause the book by running her hand up the headphone wire until she finds the button, and the same procedure can be used to play the book again. While this method does require me to manually download the books on her iPad, it only needs to be done every three to four weeks on average. For the rest of the time she is able to listen independently at the touch of a button.


Turn Off Windows 10 Annoying Features

Recently, I performed a clean install of Windows 10 Home on a new computer I built. Having mostly used Professional versions of Windows 10 or Windows 7, I was surprised with a number of inconvenient and even annoying ‘features’ that are automatically enabled in Windows 10 Home.

While some of these ‘features’ were only slight annoyances, such as advertisements in the start menu, many others have impeded in its usability. Using a number of registry tweaks and a third party Group Policy editing tool I have been able to disabled many of these features, for a more refined Windows experience.

This list represents the ‘features’ I have managed to disable at the moment. I will continue to update the list as a discover and disabled additional ones.

Automatically Downloading Apps and Games

To my immediate surprise after installing Windows, I found my fresh installation had a number of games and other apps installed.  As they did not consume a great deal of space, their installation was not a huge problem. However, I did not see the need for them to be installed when I was never going to use them.

After uninstalling the apps, I thought the process was over, however, the next time I opened the start menu, the same apps had been downloaded and installed again. Upon researching the issue, I found Windows automatically installs some apps and even reinstall them after to manually remove them.

To stop this behavior I found the following edit of the registry to be effective:

  • Open Registry Editor
  • Navigate to “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager”
  • Open the SilentInstalledAppsEnabled key and change the value to 0

App Suggestions in the Start Menu

Another feature I decided to remove was app suggestions appearing in the start menu. Essentially apps you could download from the store appeared in a small suggestions section of the start menu. The following registry tweak prevents them from appearing:

  • Navigate to “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager”
  • Open SystemPaneSuggestionsEnabled and set the value to 0

Replacing Shutdown Option with Update and Shutdown

This setting appears to be a good idea at first to ensure Windows updates are installed regularly. However, in practice I found it to cause a significant problem. One time, while working on the system, I found it to be behaving abnormally. In my experience, this was the type of behaviour that could be overcome by a reboot. However, I could not quickly reboot the computer as updates were available. My ‘restart’ and ‘shutdown’ options had been replaced by ‘update and restart’ and ‘update and shutdown’. Considering all I wanted to achieve was to quickly reboot the computer, neither of these options were acceptable.

To change this behaviour, you will need to edit the local Group Policy on your computer. Unfortunately, Windows 10 Home does not come with Group Policy editor inbuilt you will need to find a third party tool that allows you to edit the group policy.  Once you have a Group Policy editor installed, navigate to the following location and enable the policy

  • Windows Components > Windows Update > Do not display ‘Install Updates and Shut Down’ option in Shut Down Windows dialog box

Automatic Reboot for Updates

Another feature of Windows 10 Home that is difficult to like is the automatic reboots for updates. Essentially when an update is available, the computer can automatically reboot itself and install it if the user is inactive for some time. I found that while it attempted to save the state of everything you had open, it often didn’t work in practice.

To disable this feature, you will again need a Group Policy editor installed and navigate to the following Policy

  • Windows Components > Windows Update > Configure Automatic Updates
  • Enable the Policy
  • Selection an option that suits you
    • I prefer option number three “Auto download and notify for install”
    • This option automatically downloads the updates, but ultimately allows you to decide when to install them

Enable Control-Alt-Delete on Login Screen

I find having this feature enabled can be useful for Windows 10 machines when managing them using team viewer. The standard login screen can be difficult ‘slide up’ to unlock when the remote connection is not very strong. Most remote management systems provide a button to send the CTRL+ALT+DEL key sequence to the remote machine.

It can be enabled or disabled using a group policy editor at the following location:

Computer Configuration\Windows Settings\Security Settings\Local Policies\Security\Interactive logon: Do not require CTRL+ALT+DEL

UPS Power Failure Alert

For my server I am using an APC uninterruptible power supply for protection against blackouts and other power related issues. I built on my previous projects with Microsoft Flow to get a notification on my phone when my server loses mains power and when it regains it.


The software provided by APC with the UPS allows for basic functionality when power was lost, such as shutting down the computer before all battery power was exhausted. However, it did not provide any more advanced features, such as being able to run a script when mains power was lost or restored.

Fortunately, the software was creating application event logs when these conditions occurred. After some research and trial and error, I was able to deduce an application event with an event ID of 174 was produced when the mains power failed and an application event with an event ID of 61455 was produced when the mains became available again. (Both of these event logs came from the source of “APC UPS Service”)

Scheduling the Alert

To generate a notification in response to one of these events, I created a simple task in Windows inbuilt task scheduler. This task looked for the specified event ID and as an action run my notification PowerShell script that I created previously (see the previous blog post for details about the script).

The procedure goes as follows:

  • Open task scheduler in Windows and click the link to create a basic task
  • Give the new task a name and description and click the next button
  • For the trigger, select the option “When a specific event is logged”
  • Configure the event log for task manager to look for
    • Select “Application” as the log type from the drop down menu
    • In the source box enter “APC UPS Service”
    • In the event ID enter either “174” for a notification on mains power failure or “61455” for a notification on mains power restoration
  • Configure the action to be performed when this task runs
    • Select the radio button for “Start a program”
    • In the “Program/script” section, enter “powershell.exe”
    • In the “Add arguments” enter the full path to the PowerShell notification script created earlier.
    • Note: It is very important that you provide “powershell.exe” as the program to start. If you simply put the path to your script in this box, your PowerShell script will be opened in notepad when your task runs and not actually executed. This is just a feature of Windows and you will notice the same action if you double click on your PowerShell script.
  • Optionally repeat the process for the other event ID so notification will be generated for both power failure and power restoration.

JSON Web POST with PowerShell

An alternative to my previous method of using Python to make web requests for the notifications is to use PowerShell. The main advantage of using PowerShell is that it is included with Windows systems and therefore does not require the installation of any other packages. Additionally, it is far easier to trigger the script to run using the likes of Window’s task scheduler, allowing notifications to be triggered in response to events on the Windows system.

My Script

  • The first task is to once again define the URL from which the requests will be made
    • This can be found in the Flow interface under the “When HTTP request is received section” and will be unique for each flow
    • In PowerShell, variables are assigned and referenced with the “$” sign in front of them
    • $URL = "
  • Next I define a “Parameters” object to contain the parameters I want to include in the notification
    • Note: The syntax used here is to create a PowerShell object, and not JSON. It will need to be converted to JSON in the next step
    • $Parameters = @{
       "Source"= "Computer"; 
       "Message"= "42";
    • Again I am using “Computer” as the source and “42” as the message, however this will be where you can add your own custom information.
  • Next we get PowerShell to take the parameters object we just created and turn it into a JSON object
    • $JSON = $Parameters | ConvertTo-Json
    • The result is stored in the “JSON” variable
  • Finally, we perform the actual web request
    • Invoke-WebRequest -Uri $URL -Method POST -Body $JSON -ContentType 'application/json'

JSON Web POST with Python

In an earlier post, it was outlined how to setup a Microsoft Flow workflow to generate a notification on a phone when a web request was made. This post will outline how to create such a web request using the popular scripting language Python.

Install Python

  • Ensure that Python (version 3) is installed on the system
  • During this process it is important to ensure that Python is added to the system PATH variable
    • This allows Python to be called from the command line
    • Having this ability will make it significantly easier to schedule this script to run when events occur, which is likely to be the role of the script.
  • After python is installed, we must install the “requests” library
    • This is the library that we will use to perform the actual request
    • Note: It is possible to perform the POST request without the “requests” library, however I believe it to be the cleanest method.
    • To install “requests” open a command line and enter “pip install requests”
      • If you get an error running this command, it is likely that Python was not added correctly to the system’s PATH variable

The Code Itself

  • First we need to import the “requests” library we just installed into the Python script
    • This is done with the following code:
    • import requests
  • Next we need to define the URL to which the request will be made
    • This can be found in your workflow you created previously and will be unique to each Flow
    • URL = "
  • Next we need to define the JSON that will be sent in the request to provide the parameters to our notification service
    • For my notification I only had two parameters, a source and a message
    • For the purpose of this example I have set the source parameter to be “Computer” and the message parameter to be “42”
    • Parameters = {"Source" : "Computer", "Message" : "42"}
  • Finally we perform the actual request from the server
    • For the request to execute, we need to provide it with the URL and parameters we defined earlier
    • Request =, json = Parameters)
  • After running the code you should now get a notification on your phone
  • By changing the values contained in the parameters section you can change the contents of the messages to whatever you wish.
