Hello, I have a Win7 Pro License that I want to use with Win10 Pro 1511, but I can't install the Pro version of Windows 10 on the machine. It automatically installs the Home version of Win10 and doesn't ask for a key during the setup. After the installation I can't use my key, because it installs the Home version. How can I install the Pro version of Win10 on this laptop? How can I make the setup ignore the Win8 SLIC license?
