Unsure if this is directed to Windows 8.1 being stupid, or Blizzard's most recent patch for the Beta being stupid with the new file system.
After having an assertion error earlier the was preventing the Battle.Net client from loading Draenor after a patch, I decide to uninstall, and re-download the Draenor beta.
So that took 6~ hours, downloading the Draenor Beta at anywhere from 1.7 Mb/S to 4.66 Mb/S
At the final 465.3Mb of the download, Windows 8.1 locks up, freezes, becomes unresponsive, but I have full mouse control.
No other programs where running aside from the processes Windows runs.
I make an attempt to use Ctrl+Alt+Del to go into Task Manager, and Windows brings up a pop saying something along the lines of that it failed to open the screen that has these options and is needing the user to press the power button to restart.
I do that, reload Windows, and go to Event Viewer to see nothing has been logged for the time frame this event occurred.
Load Battle.Net Client back up, finish the patching that had locked up from before, and then load the game. Adjust the game settings to how I prefer, to only come across that Graphic, Sound, or Interface options are not saving. They reset everytime I reload the game back to default. Doesn't matter if I Alt F4 or Log Out properly. They simply do NOT save.
Little bit of looking into the directory, and find out that "Cache" "WTF" and "Interface" do not exist?
