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.

    I tried that but could not complete this test because Task Manager freezes up and I can't control my mouse or keyboard for long periods of time.

    Yes! Excellent diagnosis! Task Manager freezes up when Firefox is open. I confirmed that I can use Task Manager fine when Firefox is closed. Has Mozilla been made aware of the issue?

    It has been doing this ever since the Fall Creators Update.  I've tried all sorts of changes to Firefox's Performance options but nothing fixes it.  This weekend I set up a new quad core (Xeon) computer with 48 gb of RAM and a 1T SSD, and it was no better than on my worst machine.  And it's new, so nobody can blame some hidden corruption that's occurred over time.  I've seen this on every computer I own (several) and it's the same on all. I cannot believe that Firefox and Microsoft haven't addressed it yet.  Atrocious.

    Agreed! Hardware isn't an issue for me either. I am not using the machine in my original post, although that was no slouch. I am now on a Dell Precision T7600 with dual Xeon 6-core 2267 cpu's and 64GB of DDR3 1600mhz ECC ram. Still with my Samsung EVO 850 OS drive and a couple secondary drives.

    Have you seen this issue posted anywhere other than here?  I can't imagine that they don't know about it, but wondering why it's not viewed as being important enough to fix it.
