DONT run as admin let me tell you why
I did this so caled "fix and as soon as got in game I spiked from 24% cpu to over 99% cpu, running admin is like givin permission to dogs to run all across your furniture and your unlocking your gpu, and cpu ful potential with no restrictions, be wary I lost 3 freaking computers because of this game, at the end of the day you have to decide if it's worth it.
Run it normal, w/o admin rights and wait for Riot to grow some tact an actually fix the problems. btw 1,475 computers were most likely harmed in making this statement from League updates.
