Baseado em um post de um dia atrás - link
Just wanted to let you and everyone else know that I was able to upgrade from windows 8.1 pro, with user files on D:\ , to windows10 pro without any problems. Windows 10 just installed and when it was finished everything was just as it was before. I've been playing around with programs and apps and everything seems to be working fine.
It appears that there is not a need to move user files back to C:\ before upgrade.
O que seria uma excelente notícia - a restrição nunca fez sentido para mim e, embora possamos sempre realocar as pastas de documentos / etc, há uma tonelada de dados em Roaming / etc que preenche facilmente um SSD.
