I've bought a Dell XPS 15 with Windows 10 Pro. The key for activation seems to be manufactured into the BIOS/UEFI without the possibility for me to change this inbuilt key. Fine.

I decided to use a different laptop for my business operations. So I extracted this builtin key and used it for activation on the different laptop. Works as expected. I had to use telephone activation and this guy told me that now I activated my license twice. This means: I should not do it again otherwise I risk my license being blacklisted (or something).

Question: how do I install Windows 10 on the original bought Dell XPS 15 with a different Windows 10 Home key?

I am scared that if I install Windows 10 and boot it up, that it automatically tries to activate with the builtin Pro key before I have the chance to change it manually.


Here is how :

  • Disconnect the Dell from the Internet and boot.
  • Open an elevated Command Prompt (cmd)
  • Type slmgr.vbs /upk to uninstall the current product key
  • To install the new product key type :

      slmgr.vbs -ipk YOUR-PRODUCT-KEY
  • Connect to the Internet and type slmgr.vbs -ato to activate the new product key.

After entering each command wait for a few seconds till the operation completes. Proceed further only when you get a pop-up notification for each command.
