Windows 10: Do not update to K3156421 if you are using laptop

Hi,

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.

Cheers!

:)

Hi,

I think there's a difference between walking you through the steps to fix the problem and for the Microsoft to fix the problem for you through a remote session. This is the Assure Software Support Plan from the Microsoft website:

http://www.microsoftstore.com/store/msusa/en_US/pdp/Assure-Software-Support-Plan/productID.287685500

It says "... Receive one year of unlimited personal one-on-one in-store training sessions and software support from Microsoft experts via online chat, phone or in-store."

To know that your sister has the right subscription from Microsoft, ask her to log in to https://account.microsoft.com/en-us using the email she used to subscribe in the Assure
Software Support Plan. They called in Microsoft account.
