Consider the risks and benefits of each choice. Purchasing an activation key might not guarantee your files remain untouched, while upgrading to Windows 10 could reset everything you currently use. For entering a new activation code in 8.1 Pro, it should work if accepted, but switching to Windows 10 would likely erase your existing software and games.
It's merely a change in your existing Windows key. Even after upgrading, once the key expires it will be considered outdated.
Most users plan to upgrade first, then perform a complete reinstall when Microsoft drops a new ISO. I prefer a full clean install with a brand-new operating system over simply upgrading and resetting everything.
