Windows 10: Cant activate PRO license from win11 Home OEM.

Hello, i am having trouble activating a PRO license on my pc with Home OEM license. I have tried reinstalling the PC with the PRO license but that also doesn't work. When i go System ---> Activation ---> Troubleshooting ---> Recently changed hardware. it still tells me i have win11 Home msi installed. There must be a way to detach the old license?Errorcode: 0xC004C008

:)

 

Is the win11 home key keept after upgrade to win11 pro?

It probably is oem license, it came activated when i bought the pc.

If i upgrade to win11 pro and

later install win11 home (fresh install) it will activate?

 

How to Upgrade Laptop with windows home OS activated with a digital license to windows 10 pro OEM license

Hello as the title goes, I'm looking to upgrade my laptop's Windows Home OS, which is currently activated with a digital license, to a Windows 10 Pro OEM license. I've tried reformatting my laptop and installing the OS, but it automatically installs without giving me the option to enter the product key during activation. I understand that once the OS is installed, I can't change the product key in the activation settings since I have an OEM license. What are the steps I should take to successfully upgrade my OS to Windows 10 Pro using the OEM license key?

 

Windows11 Pro OEM wont be re-activated

Our organization bought 6 identical laptops including WIN10 Pro OEM. Win10 licences were activated by the selling company.

All laptops had to run same client-software, so I built 1 device and duplicated SSD (outside of the laptop) and plugged back in the SSD. All windows-clients are still perfectly registered

We then bought 6 new devices (identical to each other, different from batch 1, equipped with Windows 11 Pro OEM; not sure if the licenses were activated by the selling company.
These clients required the same build, so the vendor copied the Win10-build to these devices and arranged for correct drivers.
We have now established that our software will run on Win11, so want o perform the upgrade to Win11, and have started doing so on the second batch (the ones that came with win11 Pro licences).

The system will not allow us to activate these Windows 11 licences !!!
