I'm curious what the 'N' versions are. In the tool I noticed "Windows 10 Home" "Windows 10 Home N" "Windows 10 Pro" and "Windows 10 Pro N".

The release version is supposedly build 10240 with a different version number.

Link works for me. It lets you download a media creation tool.

It just finished downloading onto my Windows 8.1 installation. 26304

No signs of it downloading onto my Windows 8.1 install yet. Checked my reservation and it says I'm good to go.

Installed 10162, booted into 10162. Rebooted, and it reverted itself to 10159. Back to square 1...

It's preparing to install on my desktop now. I guess it auto-downloaded the update since it went straight to preparing for install.
