Notes from the Field: KB298200 – The update is not applicable to your computer

Hello Reader,

In this “Notes from the Field” post we will look at a common Skype for Business error which you may encounter when installing a Skype for Business Front End for the first time.

As you can see from the image below we have encountered an error during the the deployment wizard when installing a Skype for Business Front End for the first time on a newly built Windows 2012 R2 Server.

After downloading KB298200 and attempting to install the required Windows Update the following error occurs;

In order to resolve this issue effectively we need to download the latest Skype for Business Server Cumulative Update. This error was resolved in Skype for Business Server cumulative update Janaury 2018. A good point of reference for all Skype for Business Server CU, head over to https://blogs.technet.microsoft.com/uclobby/2015/06/22/skype-for-business-2015-cumulative-update-list/ 

First of all, you will need to stop all Skype for Business Service and this can be done easily using the following PowerShell cmdlet:

Stop-CSWindowsService

Launch the Skype for Business Update Installer and click ‘Install Updates’

Once the installation has been completed you will be able to complete the deployment wizard process with a successful outcome.

Please Note: You will need to re-run the Skype for Business Update Installer to patch the rest of the Skype for Business services.

Windows 10 Fall Creator Update 1709 – Sysprep was not able to validate your Windows installation

Windows 10 Fall Creator Update 1709 – Sysprep was not able to validate your Windows installation

Hello Reader,

In this post, we will look at a known bug within the Windows 10 Fall Creators Update 1709, where you are unable to perform a sysprep of a Windows 10 workstation running update 1709. This is a little annoying bug which prevents sysprep from running.

The error messages as shown below provides you with a bit of detail and a UNC Folder to check the log file for more information.
Sysprep was not able to validate your Windows installation.
Review the log file at:
%WINDIR%\Systems32\Sysprep\Panther\setupact.log for details. After resolving this issue, use sysprep to valiate your installation again.

This error seems to be caused by Windows 10 Store Apps updating within the background, we can prevent this from happening by adding the following reg key either by using regedit or Powershell. As I am a big avodate of PowerShell I will using show the deployment and removal of this key using PowerShell.

Identifiying the Windows 10 Applications.

Using the path provided within the sysprep error message you will be able to easily identify the problem application, this is case the problem was being caused by the SketchBook application. Once removing SketchBook app the problem persisted as a number of other apps needs to be removed also.

Video demostration.

You can find a video of each application being removed until sysprep was able to successfully execute.

We hope that this post has helped your issue.
