Opening Task Manager Slows PC to Crawl - Windows 10 Pro 1709

Hi all,

I've had an issue with Windows 10 Pro really freezing up and not being responsive after opening up Task Manager. The numbers shown for performance and CPU utilization are not pegged at all. 

This is on a Dell T3500 with a SSD OS drive, W3580 cpu, 24GB RAM, and an AMD Radeon Pro WX7100.

The computer is on a Domain with Webroot installed as AV. I usually have Solidworks and a couple of other programs open. I do not have any hardware bottlenecks as far as I can see. I also looked at the Event Viewer, and apart from a couple Group Policy warnings, nothing out of the ordinary, and no system events registered at the time of opening Task Manager.

Thanks for the insights, gents n ladies.

    After testing, this appears to only permanently fix google chrome being simultaneously with task manager.  I did not reboot; however, i did restart explorer (Rebooting would accomplish this too).

    I did this and it worked for maybe a few days and the issue came right back. So disabling powershell was not a permanent fix for me.

    I have the same issue: a crawling laptop after starting the task manager. Using Firefox and Webroot too. Using windows 10 and FCU since yesterday. A while ago I already disabled the identity protection in WR. Just to be sure I 'allowed' Firefox in WR. Nothing helps in my case.

    What I do when this happens is putting my Dell laptop in Hibernation. That going into hibernation is somewhat slower as well. Then, when starting the laptop out of hibernation, there is enough 'responsive time' to kill the task manager or save some result of other applications.

    __ edit: Forgot to mention that my hibernate button is the power button. The only key that seems to be responsive when the keyboard is not.

    Webroot was definitely the issue for me. Here are the changes I made in the Webroot UI. After this was set, Task Manager played along fine with Windows/Chrome/Firefox. 

    It would be great if anyone has any contacts at Webroot and could point them to this thread so they could optimize the application to play nicely with the OS instead of the admins having to push out workarounds and fixes for client machines.

    I had to "allow" Firefox.  Unfortunately, every time there's a Firefox update, Webroot detects it as something different and I have to allow it again.  My wife's work laptop has Webroot but making changes to it is administratively blocked out, so having to live with the problem on that one.
