Do I need to back up Windows 10 again?

Question

Iron

On my Windows 7, I successfully backed up the windows 10 update. Then, I reinstalled my Windows 7. Do I need to re-backup Windows 10 even though there is no button? And another question: how do I post a question on Answers.windows.com?

Answer 1

Why do you need a reservation at all? To, hmm, download out of turn?)) What a strange marketing.
There is an opinion that ordinary users who have not reserved Windows will be able to upgrade to it on the first day in the same way as all other victims of marketing)
