How to quickly create a Windows 10 Image in VHD format

For testing purposes I quickly wanted to create a master image using a VHD file. The Master VM was running on VMware so I decided to use the Windows 10 built-in functionality. Just run the sdclt.exe command with administrator privileges.  (This was introduced some time ago with Windows Vista).


Create System Image

Confirm your backup settings:

Confirm System Image

Sleect the Create System Image function and specify a location where you wish to store the VHD file. In this example I use a network location. Follow the default options and wait a couple of minutes. At the network location I just specified there is now the VHD file present.

Note : You can use this file also when you boot in the Windows Recovery Environment.

(Choose System Image Recovery and point to your created VHD image)

Recommended Quest Virtual Appliance specifications (K1000)

The K1000 Virtual Appliance is configured, by default, to utilize 2 vCPUs and 4 GB of memory (this is also the minimum system requirement for the K1000). However, this minimum specification is only designed for the average customer up to 1000 managed devices. For larger implementations, more resources are required.

This chart below lists the recommended vCPU, RAM and NIC specifications based on managed device count (i.e. client systems with a K1000 agent installed). This is only a general guideline, as the results can vary widely based on how the K1000 is configured. It’s possible to have less then 1000 managed devices, for example, and require more than 4 GB of memory. Details about the K1000’s performance are available in Settings > Logs, then click System Performance in the drop-down menu.

How to convert OVA to VHDX for Hyper-V 2

If you have found yourself in a scenario where you would like to use Hyper-V as a test environment for your virtual machines, but you are using VMware ESXi Server,Citrix XenServer or VirtualBox then this tutorial is for you.

Required software

  • Microsoft Virtual Machine Converter 3.0 available here.
  • WinRar (or any tool you prefer to extract .tar files)
  • Your OVA export unzipped into a folder.


  • Download and install Microsoft Virtual Machine Converter 3.0.

An OVA file is simply a tar archive file containing the OVF directory. First you rename the .ova file to a .tar extension. Now you can use WinRAR and extract the .vmdk files within to get the virtual machines disks. VMDK is an open format used by VMware and other vendors.

Convert The Image

Next we will need to convert our VMware Image in order for Hyper-V to run it. This can be done using Powershell:

Copy you .VHDX to the folder containing you Hyper-V virtual machine.  When creating your new virtual machine, you must ensure you select “Generation 1” when choosing the generation of the virtual machine :

Fixed : Dell XPS 13 (2 in 1) won’t shutdown..

After installing the latest Windows 10 Fall Creators Update I noticed that my Dell XPS 13 2 in 1 immediatly restarted after a shutdown. After some troubleshooting I noticed many other people with the same problem (also with other Dell models). The steps I found on the internet (BIOS upgrade, removing USB devices etc) didn’t work for me. But I found the solution :


Go to Energiebeheer (Power management, sorry for the Dutch language :-))


Go to “gedrag van de aan/uit knoppen bepalen” (behaviour of on/off button).


Select the first option (with the UAC logo next to in) en disable Fast boot. (Snel opstarten)

Voila! Problem solved.
