Unfortunately Microsoft has pulled the 1511 update for the media creation tool, and I need that update so that the old Windows Professional key will be recognized and I don't have to perform an upgrade first before doing a clean install.
A Microsoft apenas extraiu temporariamente a Ferramenta de criação de mídia atualizada. Se você realmente quiser usar a 1511 Media Creation Tool, ela ainda existe nos servidores da Microsoft. aqui
You can still find the 1511 version of the media creation tool on various sites, I tried that but I only get the choice between the "Windows 10" and "Windows 10 N" editions. With the non-1511 tool directly from Microsoft I got also the choice for Windows Professional there.
Você deseja escolher o Windows 10. A Ferramenta de criação de mídia do 1511 baixará uma versão universal x86 x64 do Windows 10 Home / Windows 10 Professional .ISO.
Are the installation media for Windows 10 Home and Professional actually different? Or can I install Windows Professional with a USB drive created with the "Windows 10" edition selected in the media creation tool?
Os arquivos 10240 do Windows 10 Home e do Windows 10 Professional .ISO são realmente diferentes. Este não é mais o caso com o 1511 .ISO. O arquivo .ISO atualizado é um arquivo .ISO de Home / Professional x64 / x86 universal.
