Microsoft desperately wants you to pre register. Why?

Why does it matter if you pre-register or if you don't bother
to register at all?


"Desperately"? That's your word, not theirs, and as far as I'm
concerned, the word is nonsense.

Microsoft is trying to help us with reservations. Installation can go
faster if you reserve, See
https://www.microsoft.com/en-us/windows/windows-10-faq, which says

"How long does it take to install the upgrade?

"Plan for about an hour for the installation. Newer devices may only
take 20 minutes, and older devices may take more than an hour.

"You'll need to download the installation files before you begin. If
you reserve, we'll take care of downloading those files for you and
let you know when you are ready to get started."
