    Do not update to K3156421 if you are using laptop


    After updated to the latest KB3156421 it breaks a lot of stuff for my Dell XPS 15 (9550, FHD, 84W, i7) problems are:

    1) Noticeable slow down / lag in using Chrome
    2) Poor Battery - it uses more battery and running a few degree C hotter
    3) Wake up from sleep issue- it only affect when you are using battery, it will not wake up from sleep, it shows black screen and after 10 or less seconds it reboots

    After many install / reinstall drivers I decided to try uninstall the update as I remember those problem wasn't there before the update so I gave it a try and voila all the problem mentioned are solved.

    p.s. apparently it only affect laptop using battery, DOES NOT affect the A/C power.

    Don't sink the whole ship when there is one misbehaved sailor on board.

    I have a 2 years old Acer Aspire running Windows 10 rtm, just recently updated to 10586.318 via KB3156421

    Everything is running properly as before. No issues.

    There is another thread on this cumulative update.
