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.
