Windows 7 had it's own N editions too. But if both PCs have the Windows Media Player, Groove Music or Films & TV you can forget about all that, you don't have any N editions. Those features are only available after installing the optional Media Feature Pack for N Editions. It had to be mentioned though, some reader of this forum do have N editions.
That's the Fall Creators Update, 1709. If you follow NavyLCDR's instructions and tutorial links in post #2 you'll get the install media for the April 2018 Update, 1803. This media has both Home and Pro in it, so you could just swap the drives then do a clean install of Home on your brother's and Pro on yours.Unfortunately, they have different editions. Mine's a Pro and my brother's laptop has a Home edition. But both are version 10.0.16299 and x64-based.
