14 DAY TRIAL // KB3156421 is the latest cumulative update released by Microsoft for Windows 10 November Update and just like we’ve told you today, the company is now calling for users to share feedback should they come across any bugs caused by this patch.
But before anything, Microsoft itself said today that this cumulative update comes with a known bug that makes a number of PCs very slow once it is installed on Windows 10.
Microsoft engineer John Wink explained that it’s all because of a Cortana incompatibility and it’s actually an issue that the company has been trying to track down and fix for a few weeks now.
“If you find that your PC is abnormally slow after installing the update, you may be seeing a problem that I’ve been trying to track down for a couple of weeks. Here’s something you can try to see if it alleviates the symptom. I’d love to hear the results of this test, and could really use your help in gathering additional information if indeed it rectifies the symptom for you. Please give this a shot and post your results to this thread. Thanks!” the Microsoft engineer explained.
Possible workaround
The easiest way to fix this slowdown issue caused by the update is to simply disable Cortana. And yet, if you want to continue using the personal assistant on your computer, there’s still no fix available for the moment.
In order to disable Cortana, all you have to do is to click the search box in the taskbar to launch Cortana, open the Notebook and hit the Settings button. Toggle the option that reads “Cortana can give you suggestions, ideas, reminders, alerts, and more” to off and you should be good to go.
For the moment, this seems to be the only bug caused by the new cumulative update, but we’ll continue to look into reports and let you know as soon as we come across other issues.
