Windows 10: Trouble re-activating Windows 10 Family in new VM after changes

I previously activated my Windows 10 family licensed with my ASUS laptop in Parallels VM on a free trial. As the Parallels free trial expired, I finally decided to virtualise Windows in Oracle Virtual Box. Whereas the Oracle VM is updated and visible in the list of devices in my Microsoft account, Windows installed in Oracle VB on my computer failed to detect it. As a result, I am not able to re-activate it from the troubleshooter. How to manage this? FYI, I deactivated the third-party firewall while dealing with this.

Windows Activation failed on VM

Hi,

I installed Windows 10 Pro on a VM and activated it with a freshly bought product key. It seems that there was some trouble with the VM host integration and the VM suddenly failed to start. I installed it again on another VM, activated Windows again and then had (other) troubles with the host integration.

So I wanted to install windows again on a new VM (the other VMs do not start anymore, they are garbage), without the integration, but now I can not activate this installation anymore. The Settings send me to the shop where I am supposed to buy another product key.

What can I do?

 

Problem activating Windows 11 after switching VMs

Hi there,

I purchased Windows 11 Home a couple of months ago and installed it on a VirtualBox VM. But VirtualBox was crashing quite a bit so I deactivated Windows 11 using the following commands:

• slmgr /upk
  
• slmgr /cpky
  

(as suggested on Redirecting ) and then installed it on a VMWare VM. Problem is, I can't activate Windows on the new VM even though it was deactivated on the old VM. I tried the recommended Troubleshooting Wizard solutions to no available and I couldn't find a Microsoft email address or support number, so I am posting here. Can anyone suggest how to contact Microsoft about this activation issue?

Thanks,

Darryl

PS: I have already deleted the old VM so I can't log back onto it.

 

Windows 10 VM activation

Hi,

I am trying to setup two Windows 10 vms for test purposes on Ovirt virtualization cluster. (Windows 10 Pro with MAK key from visual studio (MSDN) subscription).

Activation of the first vm encountered no problem, but activation of the second one failed. I have tried to setup second vm by all available means (by cloning from the first one with or without sysprep, from activated state or from clean installed snapshot,
by installing second vm from scratch, etc.). All are with the same results: The last product key you entered XXXXX can't be used on this copy of Windows (0xC0EA0003).

Is it possible to have several Win 10 vms on the same hypervisor, activated with MAK key?

Any suggestions are highly appreciated.
