Remove Devices

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while removing the device from your Microsoft account as it keeps popping back after removing.



It could be possible that the device was using OneDrive with the same Microsoft account and that might be the reason you are able to see the device listed under your profile. I would suggest you to remove the device from OneDrive
and see if that helps.



You can follow the steps to remove the device from OneDrive.

1. Login to
   https://onedrive.live.com.
2. Now on the left hand pane click on PC’s.
3. Now click on the devices that are listed under PC’s and on the right hand side click on
   Remove PC.

If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Using the current device's product key on my another device.

On old PC:
Uninstall retail product key:

1. Disable secure boot(if turned on in BIOS)
2. Boot into Windows
3. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.
4. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.
5. Restart
6. Wait a little while and then use the retail key on the new machine.
7. Set up secure boot(recommended)

Your old machine should go back to home, or you might need to do a clean install, I'm not sure there.
