PowerShell Script: Change the BIOS GUID of a Hyper-V Virtual Machine (2023)

Several computing functions require the ability to uniquely identify a computer. These functions will generally rely on various signatures presented by hardware components. For a physical machine, it’s expected that these numbers will be constants. For virtual machines, almost nothing is constant. Nothing is truly unique, either, as duplicates can be made through simple file copy operations. Sometimes, items are duplicated that should be unique. All of these situations can be avoided by using Hyper-V’s export and import functionality, but, things happen. This post includes a free script that easily modifies the BIOS GUID of a virtual machine.

The particular field that this script modifies (VM BIOS GUID) is also known as the system’s UUID (universally unique identifier). I know that it is used when you attempt to PXE boot a computer. If you’re here, you likely already know the reason that you care about it, so I’m not going to spend a lot of time on that particular topic. If you want to see what a computer’s UUID is, open an elevated PowerShell prompt and run the following (this works on any Windows computer, whether virtual or physical):

gwmi Win32_ComputerSystem | select UUID

I used short-hand aliases since this is something you’re typing interactively. gwmi is short for Get-WMIObject, Win32_ComputerSystem is being given to the positional ClassName parameter, select is an alias for Select-Object, and UUID is being supplied to the positional Property parameter.

The output of the above PowerShell prompt is the computer’s UUID. On a virtual machine, it is also the BIOS GUID. That is the field that this script modifies.

Warning 1: Changes to this field are irreversible without restoring from backup. Modification of the field is likely to trigger software activation events. Other side effects, potentially damaging, may occur. Use this script at your own risk.

Warning 2: The BIOS GUID cannot be modified while the virtual machine is on. It must be in an Off state (not Saved or Paused). This script will turn off a running virtual machine (you are prompted first). It will not change anything on saved or paused VMs.

The following safety measures are in place:

  • The script is marked as High impact, which means that it will prompt before doing anything unless you supply the -Force parameter or have your confirmation preference set to a dangerous level. It will prompt up to two times: once if the virtual machine is running (because the VM must be off before the change can occur) and when performing the change.
  • The script will only accept a single virtual machine at a time. Of course, it can operate within a foreach block so this barrier can be overcome. The intent was to prevent severe accidents such as Get-VM | New-VMBIOSGUID.
  • If a running virtual machine does not shut down within the allotted time, the script exits. The default wait time is 5 minutes, overridable by specifying the Timeout parameter. The timeout is measured in seconds. If the virtual machine’s guest shutdown process was properly triggered, it will continue to attempt to shut down and this script will not try to turn it back on.
  • If a guest’s shutdown integration service does not respond (which includes guests that don’t have a shutdown integration service) the script will exit without making changes.

Tip: If you just want to know what a virtual machine’s BIOSGUID is, and the above PowerShell doesn’t work/isn’t what you want to do, use this function with the -WhatIf parameter. However, because the BIOSGUID is automatically generated each time the script is run, the one that WhatIf displays will not be the one that is actually applied should you run the script again. When running without WhatIf, the GUID shown in the confirmation prompt is the GUID that will be applied.

Script Discussion

Changing the BIOSGUID has never been something that I needed to do, but I saw someone else requesting it. I noticed that all existing documentation was written for version 1 of the Hyper-V WMI namespace, which doesn’t exist as of 2012 R2. Whereas a number of WMI-based Hyper-V functions can be updated from the v1 namespace to the v2 namespace just by changing the -Namespace parameter from rootvirtualization to rootvirtualizationv2, these functions have completely different names and are not accessed through associators. So, none of those older guides will work for current virtual machines; mine will not work on 2008 R2 and earlier.

There aren’t any supported non-WMI techniques to change a Hyper-V virtual machine’s BIOSGUID/UUID. Up through 2012 R2, you can modify the .XML file directly. From what I’ve seen of the new virtual machine file format in 2016, you should be able to perform something similar using a binary file editor. However, if you don’t want to get on the bad side of Microsoft support, WMI is the way to go.

(Video) VirtualBox vs Hyper-V, What's the Best Virtualization Tool?

For a more detailed discussion of the BIOSGUID on Hyper-V, I found an article by John Howard. Most of the how-to there is useless because it’s for the older version, but you can learn more about the field itself than what I explained.
