Micah_8 :
Later this year I will be constructing a completely new system. I was wondering if I can do something as easy as plugging in my current drive with Windows 10 into the new motherboard, or if I have to use my new drive and install Windows. Anyone have any advice?
There are 3 possible outcomes when moving a drive with an OS on it to a whole new parts config:
1. It boots up just fine.
2. It fails horribly and requires a full reinstall.
3. It works, but you see lingering issues later.
Last year this time, my main PC was #2.
Yesterday and continuing, my wife's PC is at #3. It will probably require a full reinstall to 'fix it'.
Prepare for a full reinstall. You'll be glad you had it, even if you don;t need to do it.
For the licensing and activation of Win 10:
Read and do this before you change any parts:
