Hi,

After updating to the new version, I am seeing high CPU use from two processes:

Any ideas on how to make them not use a lot of CPU so that my laptop cools down and the fan stops blowing?

Hi all, 

Had the same problem myself and found the solution which is quite simple :

Go to settings -> update & security -> Windows Defender -> Open Windows Defender -> Firewall & Network protection

Then you need to disable the firewall for all the types of networks

once that's done click on restore settings

That should do the trick and you're cpu usage should return to normal.

Hope it helps, it did for me.

    When it rebooted after BSOD - all better.  Resetting networking, removing all network adapters, etc. did not fix it.  Seems to be related to internet connection sharing - I have used a CLI bat script to configure WiFi hotspot in the past - perhaps something about the new update did not like the settings that script created.

    I had a similar issue. Also caused by sharing internet connection over a virtual wifi hotspot. In my Windows Firewall settings, under inbound connection rules, there would be hundreds of rules set to svchost, all related to sharing internet connections. Removing these rules immediately made my CPU go back to normal usage.

    Looks like there is some new bug related to sharing network and the firewall.
