The stupidity of not doing my homework beforehand. Was supposed to block any URLs/IPs tonight and as I came home, someone's already been using my Wii U and thankfully left it open upon my arrival. Here's the situation: There's a popup right now saying the Wii U will start updating the system, the only choice is OK. When I go into the HOME Menu and then Download Management, there's the system update installation file fully downloaded, but it can't be removed. It says to finish installation, I must restart the console. So I'm still on 5.1.0, but it seems I'm forced to 5.1.1 anytime soon. What should I do? Is it OK to just fully power down the system or will it just install the update upon startup? Any help is greatly appreciated!!!
