I recently installed the Windows 10 Anniversary Update. After doing so however, my World of Warcraft installation started crashing during launch with a message stating Error 132 memory something or other referenced such and such.
I searched online for a solution and tried a bunch of things listed on this helpful Youtube link - the DX9 fix worked, but I found a better fix. I happened across a post listing what's new in the update and found that they "added support" for World of Warcraft in the Game DVR. On a hunch, I turned it off (in the settings of the X-Box app). Voila, WoW started working again with DX11.
Edit: After posting I found that Blizzard has an official post with the same resolution: http://us.battle.net/forums/en/wow/topic/20748004624#post-1.
