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.
