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?

Windows for home | Windows 10 | Performance and system failures

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.

    Hi,

    I had the High CPU usage after the install of 1709 so I installed an insider build to see if the usage was the same.  It was.

    I didn't have to disable anything, but I opened Settings, Update and Security, Windows Defender, open Windows Defender Security Center, Firewall and Network Protection, Restore Firewall default settings, hit the button to restore the defaults.

    The usage dropped to 1% and has been holding after numerous reboots.

    Thanks TOPMAHOF - Things seem stable right now but I will 'save' your solution in case it becomes relevant again.

    It keeps showing up for me and I have to do the fix... I'm going to experiment and not have Connectify load at startup, see if that changes anything.

    It will not work. I got an answer from Connectify. Microsoft did some changes to 1709, and now some programs are not really compatible with this version of the os. The programs work but they are causing high cpu usage. Connectify recommend me to not update the os to 1709 until Microsoft is releasing a patch for this problem, but i doubt they will. So now developers need to edit their programs so they can work fine whitout problems on Windows 10.
