    I installed Windows 10 Anniversary Update today. Please see the attached
    SL Jira link for the procedure used. This was on an Alienware laptop very similar to 2 others that reported the slowdown issue.

    This problem appears resolved by driver updates from AMD and NVIDIA.
    Please refer to Inara Pey’s Blog for more detail.

    There have been no reports of Kokua users experiencing this problem. Most likely Kokua did not have enough uses with the affected graphics cards.
