If you can wait, it'due south scheduled to gyre out to all users on May eleven.

This new update also addresses an issue that causes high memory usage for the lsass.exe process until the system becomes unstable. And if y'all have a laptop with hybrid graphics, it solves an consequence where media playback won't work on an external monitor connected through the integrated GPU while using hardware accelerated decoding on the defended GPU.
