Windows 10: Windows License for BootCamp that is No More

I was having difficulty with a machine using a Windows Pro license on a boot camp installation.


Had to wipe the machine, was able to deactivate the license, but did not get this deactivation confirmed online. How do I get the license to be transferred to new vm instance, old instance is showing up in devices.

License Activation On Apple Hardware - REINSTALL, NO BOOTCAMP

BACKGROUND:

• Purchased Windows 10 Home at Best Buy on USB stick
• Purchase Included a Windows 10 Home Product Key
• Installed Windows on iMac using Apple's BootCamp utility
  
• Windows 10 installation resides on it's own partition
• Runs perfect

THE PLAN:

• Reformat iMac Hard Drive as NTFS
• Reinstall Windows 10 Home on full drive, eliminating Apple's OSX system
  
• Use the iMac as a Windows machine

QUESTION:

Will I encounter any License Activation Issues? If so how do I deal with it?

 

Windows license problem in bootcamp and Parallels Desktop

I am a MacBook Pro user and using Bootcamp and Virtual Machines Parallels Desktop 14 in the same time. The license suppose to be able to use in both engine cause it is the same computer.

However, I activated the Windows license in the Parallels Desktop first.

Now, the Windows in Bootcamp is telling me that the product key was already used on another device.

Please help me. I do not want to purchase again the license using in the same computer.

 

Transfer Windows 10 license to another computer.

Hi,



Thank you for writing to Microsoft Community Forums.



Please note that one license key is valid only for one hardware. However you can try the steps mentioned below to check if that helps. Make sure that you have the 25-alpha numeric product key (Retail version). Here are some steps that you can follow:



Step 1: Uninstall the key from your Mac (Bootcamp). To uninstall the license key, follow the steps mentioned bellow:

1. Open command prompt (search CMD on start menu) and run it as administrator.
   
2. Then type: slmgr /upk
3. The following command will uninstall the product key from your Bootcamp partition.
   

Step 2: Install the product key on new Computer.

1. Open Run (Windows Key + R) and then type: SLUI 3
2. You will be prompted to enter the product key.
3. Please type the product key and try to activate it.

Step 3: If step 2 does not work, then you will need to install the product key manually and perform phone activation.

1. Open Command prompt once again and run it administrator.
2. Then type: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
   
   Note: replace XXXXX with the product key.
3. Once you receive a confirmation prompt that the product key has been installed.
   
4. Close the Command prompt Window.
5. Now open Run (Windows Key + R) and type SLUI 4.
6. Then choose your country and click on Next and follow the on screen instructions.

Hope this helps.
