So I've seen the Windows 10 upgrade, and I really want to do it. However, I heard that LoL didn't support it back in (5.5). Is this still the case now, or can I upgrade finally? Windows 8 is a little poo-faced biscuit. 
EDIT: Apparently it's only the Technical Preview that's out atm. Eh heh heh....
I guess my new question is: How does LoL fare with the Technical Preview?
If you're talking about that windows 10 notification in the task bar, no, you cannot. you download the upgrade after July 29th i believe.
All you can do right now is reserve your upgrade. As angrybees said the upgrades don't actually roll out until July. There is a technical preview that has come out and someone I know who has tried it said that for the most part it is a UI overhaul. He said that now it's a better experience than windows 8 for non-touch users.
Apparently you need to join the insider program to get it:
I had to upgrade my graphics card, but it works fine.
Voted "No" because Windows 10 isn't out yet. Try back after they release it.
Windows 10 isn't even out yet. It's being released on July 29th 2015. The only Windows 10 that is out right now are the beta builds which are unfinished and buggy. Windows hasn't even done RTM (release to manufacturing) for Windows 10 yet.
