It is also well known (or should be) that a clean install of Windows 10 will only activate without a product key if it is on the same computer that an upgrade from Windows 7/8/8.1 was successfully completed and activated on previously - or on which which Microsoft has granted a permanent activation for a previous Insider.
So, question to the OP:
You have a new computer. If it is homebuilt and did not come with an operating system installed by the manufacturer, how do you plan on obtaining an activation of Windows 10 clean install on it? No product key (skip entering) means no activation. The generic product key that everyone gets when they upgrade won't work to activate a clean install. You might get an activation that expires if you enter an Insider preview product key.
If the new computer is manufactured, then it should have the factory OS installed and come with it's own license for Windows.
