Right now i'm on Windows 8.1 Pro (Legacy) KMS Pico activated and i want upgrade to Windows 10 Pro (UEFI). What should be my steps for successful upgrade and activation afterwards? Also since i'm on legacy now, am I supposed to first create legacy MBR rufus bootable drive, then upgrade and create UEFI (GPT) bootable pendrive and do a clean install? Or is it possible to just clean install right away, and activate with KMS / MS toolkit? This is kinda confusing any help would be appreciated..
