Is there a way to try Windows 8.1 (legit) before shelling out the $$$ to upgrade?

[Riotvale]

Coming from a windows 7 machine. Is there a way I can try Windows 8.1 before I commit and spend some $$ on the new OS?

I haven't even seen 8 in action, and would like to see how it runs.

Looking for legit methods
