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 https://answers.microsoft.com/en-us...d-on-old/f7f1ba9d-ba45-4394-9bbd-4d4d2c466879 ) 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.

0xC004C008 - Activation fails in Oracle VM VirtualBox

Hi,

after installing Windows 11 on Oracle VM VirtualBox in settings window I get message Activation State - Not Active (We can't activate Windows on this device because the product key was already used on another device. If you think it wasn't used on another device, select Troubleshoot below. Error code: 0xC004C008.)

Before installation on Oracle VM VirtualBox I installed it on Gnome Boxes. Due to low performance I removed Windows 11 installation from Gnome Boxes and installed it to Oracle VM VirtualBox where performance is great.

When I press Troubleshoot button, and go through sequence of questions it ends up with error: Oops... We encountered an unexpected issue. Please try again in sometime.

I tried manually enter new key in Terminal using slmgr.vbs -ipk ... which gives me message that product key was successfully entered.

Sincerely,

KB
