Build 10586.318 is running abnormally slow, here's a possible fix

[BoraMurdar]

Microsoft's John Wink, Senior Program Manager Lead working on Windows 10 updates, said on Reddit today that "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."

He continued:

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!
Steps to disable Cortana: Click in the Cortana search box to bring up Cortana
Click the Notebook
Click Settings
Move the slider under “Cortana can give you suggestions, ideas, reminders, alerts and more.” to “Off”.
Thanks!

In reply to another comment in the thread, he also noted:

It's actually not a very wide-spread issue, it's just that when you hit it, it's incredibly annoying. If disabling Cortana resolves the symptom, that means we know what's happening and we'll probably roll a fix into a future update. But I need some examples of cases where this workaround works to justify rolling that fix in.

My only problem is the update now. I installed the updates and after the restart the Windows wants to install it again but stuck in the downloading process. Interesting!

Try going to Control Panel\All Control Panel Items\Troubleshooting and click on Fix Problems with Windows Update

So, they knew something was wrong with the update, but released it anyway...

It tried to install twice on my system -- after already being installed and got stuck in loop.

My updates was successful, but I did notice that it took much longer than usual to complete on both my desktop and laptop.
